Statutory old-age provision How the pension is financed

Status: 21.06.2021 10:35 a.m.

It is and should remain the foundation of the old-age provision of millions of Germans: the statutory pension. How does our pension system work and what are the challenges it faces?

From Andreas Braun, tagesschau.de

How is the statutory pension basically organized?

The statutory pension in Germany is organized according to the so-called pay-as-you-go system. Those who pay in do not build up a capital stock that they can fall back on in old age, but rather finance the current earnings of the current pensioners. Anyone who pays into the statutory pension thus acquires a right to such a pension in old age, for which the next generation then has to pay. After a certain waiting period – currently five years – this entitlement is given. In order to receive a pension, you must also have reached a certain age (currently 67 years as a rule).

Who pays into the statutory pension fund?

Employees in Germany are required to pay into the statutory pension. Employers take over half of the payments into the pension fund. The contribution rate is currently 18.6 percent, so 9.3 percent each comes from employees and employers. Self-employed, freelancers or people who are not gainfully employed can also make voluntary contributions. All contributors acquire pension entitlements to which a certain pension amount corresponds. It is determined by so-called “remuneration points”.

How much does the federal government pay into the pension fund from tax revenues?

Since the income from contributors has long been unable to cover the expenses of the pension fund, the federal government co-finances the fund through tax revenue. In 2020, these expenditures exceeded the 100 billion euro mark for the first time. The federal budget provides 106 billion euros for 2021. That is more than a quarter of the federal budget. According to experts the proportion could rise to more than 50 percent of the budget in the coming decades .

What caused the deficit in the pension fund?

The demographic development in Germany is the main reason: The number of people paying into the pension system is facing an increasing number of pensioners. In 2020 there were 57 pensioners for every 100 contributors. In 2050, it is estimated that 100 contributors will make payments for 77 retirees. Since the pension level has always been adjusted upwards in line with the general wage level and there have been no pension cuts, the deficit is growing steadily.

What is meant by the “sustainability factor”?

In order to be able to take into account the ratio of contributors to pension recipients when calculating the pension amount, the “sustainability factor” was introduced in 2005. It should lead to the fact that the pension increases are dampened with an unfavorable ratio of contributors to pensioners. However, only a quarter of the factor is included in the calculation.

What are the “stop lines” set by politicians?

The legislator has provided so-called stop lines, which secure the pension level and at the same time limit the contributions to the pension fund. It is planned that the pension level (with 45 years of contribution) will not fall below 48 percent of current average earnings by 2025. A second stop line relates to the level of contributions from employers and employees. The contribution rate may not exceed 18.6 percent until 2025.

Why is the situation in the pension funds worsening?

The increasingly unfavorable ratio of contributors to pensioners – together with the state guarantees for the amount of pensions and contributions – will further exacerbate the funding gap in the pension insurance scheme in the years to come. The federal government has not yet made any fundamental changes to this system.

What are the options for reforming the pension system?

Proposals for reform target both the revenue and the expenditure side of the statutory pension insurance system. In order to increase the income, either the contribution rates could be increased. In addition, statutory compulsory insurance is also being discussed for additional groups of people such as self-employed or civil servants. On the expenditure side, the pension amount can be reduced on the one hand, and the retirement age can be increased on the other. A link to general life expectancy, for example, is conceivable. The income from the contributions paid in, and thus also the future pension amount, could also be increased by investing more contributions in the capital market.

What should the insured expect in the coming years?

The growing imbalance between income and expenditure in the statutory pension insurance will make reforms necessary in the coming years – economists and politicians of the most important parties see this equally. Contribution rates are likely to rise while average pension levels are lowered and working lives are further extended. In any case, it is likely to become even more important for the insured to make private provision for old age

Edit | Li Shuiqing Wisdom News reported on June 21 that the GTIC 2021 Embedded AI Innovation Summit recently concluded successfully in Beijing! At this high-profile AI industry summit with a full audience and more than 1.5 million live viewers on the entire network, 16 bigwigs from the upstream and downstream of the industry chain gathered together to focus on the software and hardware ecological innovation of embedded AI, home AIoT, Mobile robots and industrial manufacturing industry 4 major sections of the map, bringing in-depth and simple to share. At the meeting, Chen Chao, the R&D director of Jizhijia, gave a speech titled “Challenges and Innovations in the Visual Perception Technology of Logistics Robots”. The speech mainly consists of three parts: logistics and logistics robots, and the challenges and solutions faced by logistics robots in vision in two different scenarios: warehousing and industry. The logistics industry is a huge market, but the industry has long faced pain points such as difficult employment and rapid changes in market demand. Logistics robots came into being under such a background. At present, they have evolved into multi-scenario product forms such as smart sorting, smart handling, smart forklifts, smart warehousing, and so on, and have landed in many practical scenarios. Chen Chao recalled that, in the process of launching the logistics robot of Jizhijia, many challenges have been overcome in terms of visual perception technology. In the field of warehousing AMR mobile robots, the scenarios are relatively simple, mainly including picking from shelf to person and picking from box to person. For the ground two-dimensional code used for navigation, the team encountered problems such as defacement/reflection, motion blur, and demands for cost reduction. To this end, Gzhijia introduced V1.5 based on the fusion of ground patterns on the latest robots to make up for the problem of easy fouling of the QR code; further, Gzhijia’s V2.0 solution based on Marker-Net reduces the failure rate Reduce by two orders of magnitude. In the field of industrial AMR mobile robots, the scenarios and challenges are more complex and diverse. For example, in response to the problem of fewer samples in the industry, Gigabyte adopts a learning simulation program to quickly expand the sample; for the problem of unknown target detection, Gzhijia introduces a depth camera, which allows the deep learning model to organically combine deep data to improve target detection performance. For the problem with high robustness requirements, Gigabyte adopts a composite model method; for positioning problems in high dynamic scenarios, map update and semantic maps are used to ensure long-term stable operation of the robot; for end-side equipment with low computing power The problem is that Gigabyte uses algorithm optimization and acceleration engine to break through the limit of computing power. It can be seen that, as a logistics robot head company established in 2015, Jizhijia has overcome the hills of embedded AI development for specific application scenarios in warehousing and industry. We organize the record of Chen Chao’s speech into the following three parts: 1. The logistics industry accounts for over 10% of GDP, and logistics robots came into being Regarding logistics, in addition to express logistics that ordinary consumers often come into contact with, it also includes subdivided logistics scenarios such as warehousing logistics and factory logistics. Logistics is a very complex and complex industry, accounting for more than 10% of GDP. It can be said that logistics provides a guarantee for the supply of production and living materials for the entire society. In recent years, the logistics industry has faced challenges: the first is the difficulty of employing people. In fact, everyone around them can clearly feel the trend of aging and declining birthrate of the entire society over the years. The working-age population is gradually decreasing. At the same time, young people nowadays are more inclined to go to big cities to engage in service-oriented jobs. They are unwilling to go to factories and warehouses to do some low-level boring logistics jobs for logistics-related companies. Recruitment caused certain difficulties. On the other hand, the logistics industry is changing rapidly. With the development of the entire economy, residents’ consumption upgrades. At present, there are fewer and fewer large-scale standard industrialized products, and more are highly customized and personalized small-batch production. Now the product iteration speed is faster and the upgrades are more frequent. , To present new challenges to the supply chain. Logistics robots came into being in this context. Since logistics involves a wide range of areas, there will be different robots and solutions in different links and aspects. (Logistics robots) are mainly used in smart sorting in some express delivery fields, smart picking in e-commerce warehouses, as well as smart handling robots, smart forklifts on manufacturing production lines, smart warehouses and smart factories for integrated solutions… below, Let’s find out through specific robots. Jizhijia’s family portraits cover most of the categories of logistics robots. Including the low and latent picking robots and handling robots in the front row, as well as the sorting robots and bin picking robots in the middle, as well as the tall unmanned forklifts, man-machine collaborative robots, and composite robots with robotic arms in the back row. Behind the busy robots is a cloud-based system architecture. First of all, on the bottom side is the body of the robot, which contains software algorithms such as visual perception, positioning, and PNC; on the edge server side in the middle, running RMS is responsible for robot task scheduling and path planning; the top cloud deployment WMS, ERP The system is connected with the customer’s business. It is based on such a cloud side-end architecture that (we) guarantees the stable and efficient operation of logistics robots. 2. Warehousing scene: The accuracy of visual recognition needs to be improved, and there is a big demand for cost reduction After having a preliminary understanding of the logistics robot system, take a look at the challenges and responses of visual perception. First of all, in the warehousing scene, the current applications are: 1. Picking from shelf to person; 2. Picking from box to person. “Goods-to-person picking mode” has changed the traditional way of picking and choosing people to find goods-the RMS issues instructions, the robot runs to a specific location, and the corresponding shelf or specific bin is transported to the picking station. Picking is done manually. In this link, operators no longer need to shuttle shelves to find goods. The new picking mode greatly reduces the labor intensity of pickers, and at the same time significantly reduces the error rate of picking, so that the overall efficiency is improved by 2 to 3 times. How is the picking robot positioned? Careful friends have already seen that in the video, some QR codes are densely gridded on the ground. A camera is installed at the bottom of the robot. The camera uses the camera to capture the QR code for positioning. This is similar to the principle of scanning codes on mobile phones. Since the QR code is deployed on the ground, there are some special features that are easy to be defaced. In the warehouse scene, there are often some trailer trucks in operation. The warehouse is regularly cleaned and maintained. Using a very powerful washing machine will cause damage to the QR code on the ground. On the other hand, the robot runs at a speed of more than 2 to 3 meters per second, the lens is very close to the ground, and the number of pixels that the object slides in a unit time is relatively large, and the image blur is more serious. In addition, low cost is also subject to fierce competition in the front-end market. The (market) puts forward a demand for cost reduction for picking robot sensors and computing chips. In response to the previous problems, we have made some iterations of technology and products. In the earlier version, a very low-cost heterogeneous SoC (System-on-Chip) was selected, and our traditional geometric feature-based algorithms were optimized and accelerated by FPGA, and finally achieved a relatively excellent performance-to-price ratio and performance-to-power ratio. Aiming at the problem of the contamination of the QR code, and also in order to reduce the deployment of the QR code in the scene, (we) introduced the ground pattern. If you look closely, you will find that the ground actually has very small textures, which are unique IDs, which can be used for positioning, which is similar to the code value on the QR code. Due to the particularity of the land pattern, (we) adopted a series of transformations to extract the global feature of the land pattern and establish a map location. Of course, the ground pattern has certain limitations, and it cannot be used for the epoxy floor of the factory and some high-gloss tile floors. (We) deploy a head-up camera on the front end of the robot, and use a neural network method Markernet on the back end to greatly expand the two-dimensional code detection capability on the latest robot. Previously, our camera was shooting downwards, and the field of view was very small. If the robot deviated a little, the positioning would be lost in a few centimeters or ten centimeters. Now relying on the front-view camera can detect the QR code in a larger range and perform relocation, which reduces the failure rate by two orders of magnitude. Many friends will ask, why use the network method for objects with obvious geometric features or artificially designed QR codes? Compared with the traditional mobile phone scanning code or the previous robot looking down the QR code detection method, now the QR code needs to be detected in a larger range and smaller angle to detect the fuzzy and contaminated QR code, based on the data-driven model method Exceeds the traditional method of artificially designing features. With the help of flexible camera deployment and back-end intelligent algorithms, the use of QR codes in the scene is greatly expanded, and it can be extended to side shelves or ceilings or almost anywhere in the scene. This is a test done in a logistics port container, which can detect and recognize the QR code in a very dark environment. 3. Industrial scenes: to deal with more complex scenes and establish simulation schemes In the industrial scenario, the challenges and responses faced by the visual perception of logistics robots, compared with the previously mentioned warehousing environment, involve more operations and a wider range. In the industrial scene, there are different types of robots in different scenes, including the roller handling robot on the left, lifting and handling, as well as robotic arm load robots and smart forklifts. In the industrial scenario, the requirements are diverse and the scenarios are complex, and different robots face different challenges when dealing with different tasks. Let’s take a look at it in detail. First, there are few samples. Take compound robots as an example. In the end-grabbing process, they are faced with the detection and recognition of more than 100,000 commodities. Unlike applications such as unmanned vehicles, few in the industrial field can find corresponding ones on public data sets. Samples for our training. At the same time, industrial customers have certain requirements for data privacy, which also restricts the collection of some samples. We adopt a simulation + learning program. Take pallets as an example. Pallets are vehicles that are widely used in the entire logistics scene. There are many types of pallets, including European standard, national standard and non-standard. There are various colors, shapes, sizes, materials, and even some customers. Take local materials and temporarily assemble them into pallet-like items with raw materials. Use the simulation engine to quickly build a single-target rendering, which can be rendered with different lighting, colors, and positions, and quickly expand our samples. For some applications, we can do full-scene simulation. Few Shots learning and Transfer Learning are used to quickly develop and adapt some new applications for some of the data that has been accumulated before in the industrial scene and the models that have been trained. Unknown target detection, there are many types of targets, some anomaly detection or obstacle detection can not exhaust the tested targets, we don’t know that the wrench or a part on the production line is dropped in front, or it may be a mouse or battery, based on the traditional The depth model method relies too much on the previous samples, and when faced with the detection of items that have never been seen before, the performance has a relatively large drop. We introduce deep learning methods to organically combine depth data and RGB data for detection. There are many types of depth cameras, including Stereo camera, TOF camera, Structure Light camera, etc. Choose the corresponding sensor according to different detection distance and accuracy requirements. We use Stereo camera for obstacle detection. The output depth map and grayscale map are naturally aligned on the pixel level, which is very good for the further information fusion in the future. The depth-based detection method does not rely on the previously established model, and has a better detection effect for unseen targets. Our robot uses a very cheap depth sensor, which is not as high as a lidar. Accuracy. For low and small objects, the availability of depth data is greatly reduced. For very distant objects, the depth map degenerates into a 2D map in principle, which needs to be combined with RGB data for detection. In the industrial scenario, due to the requirements for safety and efficiency, the robustness of related equipment is very high. Take forklifts as an example. The load capacity of forklifts is very strong and the destructiveness is very large. Error detection will affect items and personnel. Caused very big damage, we adopt the method of compound model, combine deep learning method with domain knowledge through compound model. On the one hand, we quickly output the potential detection objects of the object. On the other hand, for pallet detection or certain bin detection, we know what the detection target is, we can use the prior model to perform a network verification to obtain robustness Higher accuracy and higher results. Positioning in high-dynamic scenarios is different from warehouse robots based on two-dimensional codes on the ground. SLAM robots are used more in the industry. SLAM is a technology that uses sensors to observe the environment to establish a map and then locate it. This is very similar to the principle of human eyes observing the entire scene and positioning based on these visual landmarks. SLAM-based positioning has some advantages. There is no need to modify the scene, and there is no need to lay so many two-dimensional codes. It is more convenient to implement. The walking route is not gridded, but an arbitrary trajectory. Due to its flexibility, SLAM robots are more in line with the needs of customers in the flexible manufacturing industry and have been widely used in the manufacturing industry. A very big challenge based on SLAM positioning is the problem of positioning loss in a high dynamic environment. For example, the bins on the production line will change with the change of work time. When the robot picks up the bins, there are still 10 bins. When it is put back, only 2 bins remain, and the scene changes If the robot fails to locate, it is equivalent to holding the old map to look at the way and find the way, and it will probably fail. We adopt a map update and semantic map solution. Based on the cloud-side end architecture just mentioned, each end-side robot is given the ability to detect changes. When it finds that the map does not match well, it uploads the data to the edge server. The edge end can integrate the data collected by multiple robots, judge based on the previous static reference map, perform map fusion update, and send the fused map to each robot, so that the robot can use the latest map for positioning. Semantic map detects some objects in the network and recognizes dynamic and static characteristics. For example, people and material trucks are movable and cannot be removed from the map as landmarks. For some heavy equipment, they are movable and the movement frequency is very low. Decrease its confidence in the map. The markings on the ground, walls, pillars, etc. are highly static objects, increase its confidence in the map. Compared with traditional feature point-based positioning, the accuracy of semantic target-based positioning may be slightly lower, but the robustness is very high. It can even partially or fully constrain the position of the entire robot based on one object in the entire scene. , So as to ensure the smooth operation of the robot. The challenge of low computing power is limited by a series of factors such as price, size, and power consumption. It is impossible for us to use high-performance computing chips on end-side devices. What we do is to optimize at the algorithm and software level. For the network model, optimization is performed on the numerical calculation level, the structure of the network itself, and the entire detection process. On the other hand, we use the supporting optimization and reasoning engines provided by major hardware manufacturers to optimize the deployment of our algorithms. Taking OpenVINO as an example, quantitative tuning and pruning are performed on the server side, and the optimized model is deployed on a low-computing computing platform through the IE engine. Intel’s OpenVINO can fully tap the entire processor, not only the CPU, but also other computing units, especially the computing power of the integrated graphics card, making full use of on-chip resources. Let’s talk about it today. We look forward to working with colleagues and partners to discuss the application of visual AI technology in the logistics industry, and to build intelligent robots to make logistics easier. thank you all! The above is a complete compilation of Chen Chao’s speech.

The 75 meter high eucalyptus tree includes 165 steps to challenge Australian adventurers Many visitors describe the experience of climbing the 75-meter ‘Dave Evans Bicentennial’ ancient eucalyptus tree as intimidating. Of course, the trip is not for those who are afraid of heights. Around the tall tree, people plug 165 ‘stairs’ which are iron stakes attached to the winding tree trunk. The Dave Evans Bicentennial eucalyptus tree, located inside Warren National Park, near Pemberton, West, is Australia’s highest fire observation site. The first time people inserted iron steps into a tree trunk was in 1988, marking 200 years since the arrival of British ships in Sydney in 1788. Now, this giant tree has become an attraction for adventurous tourists who want to conquer the towering tree and enjoy the panoramic view of the green national park. Adam Scott, a TikTok user shared a video of his recent conquest of a giant tree. According to Adam Scott, the only way to go up is to step on a series of iron bars hammered into the side of a tree more than 30 years ago. Adam Scott, who owns a TikTok account with more than 28,000 followers, said: “This is definitely Australia’s scariest attraction. This thing is so sketchy, how have they been around for so many years. “. In his first conquest, Adam Scott climbed to a height of about 25 meters above the ground. There are no seat belts or any instructions. On the way to climb the tree, there will be only you and the space seems to have no end under each iron stake. “If you fall, there won’t be anything to support you,” says Adam Scott. On the TripAdvisor page, many tourists who have joined the journey share that ‘if you are a thrill-seeker, you will love this adventurous tree climbing trip’, ‘Tree climbing is a great experience but sure. Not for the faint of heart’, ‘The distance between the stakes is very large so be careful’, ‘Although the distance is very large and 75 meters high, no one has actually died while climbing a tree’… To participate in this unique experience, you need to buy a Warren National Park pass, 12 USD, or about 276 thousand VND per vehicle, at the Pemberton Visitor Center. Then, traveling by car for about 15 minutes, you will see the old Dave Evans Bicentennial tree.

Theoretically, the limit of low temperature in the universe is called “absolute zero”, the value is 0 K, converted to the commonly used temperature unit of -273.15 degrees Celsius. And to prove the existence of absolute zero, mankind has had to conduct a lot of experiments over a very long time and the story of this limit value is also quite interesting from a scientific perspective. because when the concept was introduced, no one could conduct experiments near that temperature. But the specific concept of absolute zero was not formed overnight, instead it was studied, observed and concluded by generations of scientists. As early as 1702, the French physicist Guillaume Amonton questioned whether there was a limit to cold. He improved a thermometer that used air and mercury. The volume of air changes with temperature, causing some of the mercury to move to show the scale. The minimum value of the thermometer has a limit, which is the point 0 (according to today’s calculations, it is about -240 degrees Celsius). Until the end of the 18th century, many physicists tried to discover this low temperature limit. In 1785, Jacques Charles, a French physicist discovered the relationship between the temperature and the volume of a gas at constant pressure. In his experiments, he found that in the case of constant volume, for every 1 degree Celsius decrease, the pressure of the gas will decrease by 1/273 of its pressure at 0 degrees Celsius. According to this rule, when the gas temperature drops to -273 degrees Celsius, the pressure becomes zero – vacuum environment. Later, the English physicist William Thomson (ie 1st Baron Kelvin) gave the first formal form based on the summation and speculation of his predecessors about the concept of absolute zero – understood as a state in which the interior of the object can be reduced to zero and completely stop the motion of the molecules. Accordingly, one of the ultimate goals in the field of thermodynamics is a great battle to challenge absolute zero. And of course, this goal cannot be achieved overnight. Michael Faraday. The first major figure in this race was Michael Faraday. By 1845, he had obtained various forms of liquid gases through primary compression. With his technology at the time, he was able to achieve temperatures as low as -130 degrees Celsius. However, during that time he was still unable to liquefy some gases such as oxygen, nitrogen and hydrogen. This was due to theoretical limitations at the time, so Faraday believed that these gases were “permanent gases” and could not be compressed into a liquid state. In the late 1870s, French physicist Louis Paul Cailletet pioneered the production of liquid oxygen and liquid nitrogen, which could be obtained at low temperatures of -183 degrees Celsius and -196 degrees Celsius, respectively. To achieve this, Louis Paul Cailletet applied the Joule-Thomson effect. James Dewar. The next important person was a Scottish chemist and physicist – James Dewar, who would challenge hydrogen, the last “eternal gas” at the time. Scientists at the time expected to be able to produce liquid hydrogen at as little as -250 degrees Celsius. This temperature was an impossible challenge with the technology and equipment at the time, so Dewar had to invented new devices to be able to conduct this research. His plan was to use a gas that could be compressed and liquefied at room temperature, then allowed it to expand and return to a low temperature and then continue to use this temperature to liquefy other gases that are more difficult to liquefy . In this way, after a series of stages, it is possible to reach a temperature low enough to liquefy the hydrogen. But to do that, Dewar was forced to create new equipment and tools for research, which required a lot of money. So Dewar demonstrated some of the unique properties of liquefied petroleum gas to guests in the Royal Society’s laboratory, and used experiments to attract investors’ attention. But the experiment didn’t go well, in 1886, a terrible explosion occurred in a London laboratory, Dewar accidentally mixed liquid oxygen with liquid ethylene and caused an explosion, which subsequently caused the His scientific career was almost over. Soon, however, Dewar produced 20 cubic centimeters of liquid hydrogen through a multistage cascade of methyl chloride-ethylene-oxygen-hydrogen. At that time, the tank had a pressure of 180 atm (atmosphere) and the temperature reached -205 degrees Celsius. Dewar then put liquid hydrogen into the expansion tube and watched the temperature of the thermometer gradually decrease, eventually, he achieved a new record of -252 degrees Celsius, considered to have completed the impossible challenge for the predecessors. Faraday duty. However, shortly after the experiment was successful, a new gas was born – the inert helium gas. Next, Dutch physicist Heike Kamerlingh Onnes went on to undertake this research and built a factory to produce magnetic liquid hydrogen using Dewar’s equipment and miraculously produced liquid helium, reaching temperatures lows of -269°C (4.2 K). At this near absolute zero temperature, many substances will exhibit unprecedented states, including fluid mechanics, electromagnetism and other related properties, which also earned Onnes the Nobel Prize in Physics in in 1913. But so far, no one has been able to conduct an experiment to achieve theoretical absolute zero – the value is 0 K, converted to the commonly used temperature unit of -273. ,15 degrees C.

TikTok wants to encroach on e-commerce. (Image: Bloomberg) TikTok wants to repeat the success of Douyin – the version of TikTok exclusively for the Chinese market. Only in the first year, Douyin earned 26 billion USD in e-commerce transactions. According to Bloomberg, TikTok has started a partnership with a number of brands so that they directly sell products to millions of users right on the app. It is not clear when TikTok will officially announce the feature. A representative of Hype, one of the brands TikTok partnered with, confirmed the experiment. According to images provided to Bloomberg, Hype’s booth in TikTok displayed a range of products with photos and selling prices. ByteDance – TikTok’s parent company – is actively exploring the Chinese e-commerce market in the hope of writing another glorious medal in the company’s history right before the IPO. The company aims to process more than $ 185 billion of global e-commerce transactions by 2022 based on the reach of TikTok and Douyin. Unlike Alibaba, Tencent, ByteDance’s app is well known globally. Founder Zhang Yi Ming wants to use it as a stepping stone to the online shopping game. ByteDance remains a slowdown in China’s “social commerce” market, where celebrities sell products to followers. In the email, TikTok said it is experimenting and learning, and constantly discovering many new ways to add value. Currently, the major social networking companies are scrambling for online retail market share, a market expected to generate $ 5 trillion in sales this year. In May 2020, Facebook introduced a new tool to improve the shopping experience on Facebook and Instagram. Pinterest also jumped into the e-commerce market when it brought buyers to the seller’s website. For its part, TikTok has challenged the online shopping market through promotional campaigns with Walmart and Shopify. Businesses often mark products on TikTok content, with a link that leads buyers to their own website, but all of it takes place within the TikTok application. TikTok wants to lock users down more tightly by allowing brands like Hype to run booths on the platform, take orders and interact directly with buyers. TikTok hopes to sell more ads to sellers, increase traffic and eat commissions. In December 2020, Zhang told TikTok employees that e-commerce, when combined with short videos and livestreams, offers even greater opportunities outside of China. The company has quietly built up a team of engineers in Singapore to develop its e-commerce business. It is very likely that TikTok will successfully re-establish with videos suggested by artificial intelligence when it comes to shopping online. Du Lam (According to Bloomberg)

Modern boats take tourists about 7km from the mainland in the Aliwal Shoal (PV Dinh Luong at the far right). South Africa in particular and Africa in general attracts tourists with its pristine beauty, mystical indigenous culture and with 5 large species of “Big Five” including African elephants, Cape buffalo, leopard, lion and Rhino. But there is a different South Africa from the trips adventure travel Swim with sharks at Aliwal Shoal Marine Life Reserve, Umkomaas Town, KwaZulu-Natal Province, South Africa, about 50km south of the provincial capital Durban. Here’s your chance to meet these amazing creatures face-to-face throughout your life, a new adventure experience that challenges logical thinking and does what you never thought you’d ever do – in the water surrounded by sharks. Wondering if you can’t swim, can’t swim well, or are afraid of risking your life? All you need is an adventurous, adventurous and challenging spirit as the tour organizers will offer you a variety of options – from near absolute safety to the ultimate test of willpower. . You can simply drop yourself inside a stainless steel cage approved by the Maritime Safety Authority of South Africa (SamA) with a safety mask, choosing from different degrees of shallow depth when standing in the cage according to your preference. . But prepare for adrenaline rush with a more adventurous and memorable option. Many different options when diving with sharks. (Photo: Dinh Luong / Vietnam +) We came to Aliwal Dive Center because it is a diving center with sharks with more than 28 years of experience. Answering my concerns and worries when considering bringing both my wife and two children to the shark experience diving tour – guide and diving expert with the shark Danie Bester said he has more than 4 years in job and no mistakes have occurred. Aliwal Dive Center is part of an effort to conserve marine life, including sharks in the Indian Ocean, around the coastal city of Durban. Leaving previous jobs in Pretoria and Johannesburg, Danie chose to guide diving with sharks, because he could do what he loved and wanted to contribute to changing the animal’s perception. After helping with the selection of swimsuits, propellers and waterproof masks, Danie carefully told us to keep our arms closed under our armpits, use the propeller to swim softly, avoiding the shark’s mistaken hands other small fish species for food and attack. Strictly complying with the requirements for medical reporting during the COVID-19 pandemic season, my family of 4 and my friend Lina, 17, a South African citizen of Indian origin join a shark diving tour. . Lina’s parents pleased their daughter but still worriedly sent off to the beach and waited. Surf safely on custom 8m Superduck Semi Rigid boats equipped with a Yamaha Four Stroke 2×100 HP engine, to the area south of Aliwal Shoal, where skilled guides say there’s plenty of fish fat. The modern motor boat takes the group about 7km from the shore, the water depth is 20-30m. Sharks head to the ocean from many directions. (Photo: Dinh Luong / Vietnam +) We are fortunate to have a beautiful International Labor Day, the sea is relatively calm, the water is clear, the sunlight helps the view to the sea floor. In the breeding season from July to November each year, sharks often gather in high density in this sea. Captain Keith Rousouw with 25 years of experience instructing diving with sharks directly steered the boat. He said a support group of four divers on another boat helped us attract sharks, using food from small marine fish that was prepared and strictly followed the Ministry of Environment’s Shark Diving license. South Africa. The stainless steel cage floats on the water thanks to two buoys. The cage designed and perfected by an engineer can accommodate 8 people at a time, providing a relatively comfortable space for 4 visitors on this discovery tour. You might be wondering with the number 4? I chose to swim with Danie right from the beginning after consulting with these two skilled experts. Danie let me hang on a floating wooden stake thanks to two large floats, attached to the iron cage, for a wider view and better experience. You can feel my worries more clearly when you have seen the shark videos. The Oceanic Blacktip is 1.5-2m long, stout body with pointed snout, long gill slits and no burrs between dorsal fins. This species reached a maximum known length of 2.8m and a maximum weight of 123kg. Most individuals have a black head or edge on pectoral, dorsal, ventral, and caudal fins. Danie was in the water directly with us and Keith watched carefully from the boat. Expert Danie in turn helps team members cling to the wooden stake and swim with each person closer to the sharks. The experience of diving and being up close with the sharks affirms Danie’s love and understanding for this fish – calm and flexible. Between the time diving and underwater observations, I rose to the surface to breathe but many times saw the tall and crescent-shaped front dorsal fins of the ocean blackhead sharks moving around in the afternoon. It is about 1.5m long and weighs about 50-70kg, according to Danie. The blackhead shark is an agile and energetic carnivore. Oceanic Blacktip can jump out of the water while attacking small schools of fish. Their demeanor has been described as “timid” compared to other great globular sharks (family Carcharhinus), which are common in coastal tropical and subtropical seas around the world, including lips. brackish water habitat. We assessed that we had met about 25-30 marine blackhead sharks during the trip, but Danie said there were about 17 (perhaps due to anxiety, so amateurs “look nationalized chickens”). Many times while swimming next to Danie gets closer to the sharks, it feels as if they are rushing towards you, but with a graceful turn. Although I have had very close experiences with these ferocious animals, to a certain extent, I have to admit that they seem to be very friendly. And to be very restrained, we do not reach out to touch the flexible swim bodies very close – which expert Danie always warns to absolutely comply. Not only having a diving experience with sharks, the trip brings an understanding of other creatures living in shallow waters below 40m and small, symbiotic fish always “side by side” with the sharks. Another plus point is that you will experience surfing on a modern boat controlled by skilled captains. Goodbye, Ms. Basie Aukermann, Director of Aliwal Dive Center, said that the Center has actively and silently contributed to the conservation of marine life at Aliwal Shoal Protected Area and is delighted to have tourists from Vietnam. The distant south has come and experienced. Nature has its own ways of functioning, and South Africa is not just famous for the Big Five on land. The land of great experiences to challenge the will and adventure, to explore. Expert Danie Bester (left) supports journalist Dinh Luong on adventure travel. (Photo: Dinh Luong / Vietnam +)

Album Into The Woods Mr. Dang Cong Nhat (HCMC) recorded a 2-day and 1-night picnic in Lac Duong forest, pursuing a type of Vintage camping (traditional camping). “We chose Lac Duong because this location is not too difficult to go, moreover, the terrain and climate suitable for the vintage fashion we pursue”, Mr. Cong Nhat shared with Zing. “Unlike normal travel, nature discovery journey offers a more enjoyable experience,” he said. The trip has a style similar to wildlife survival but is not challenging but aims to be in harmony with nature and explore your own limits. The necessary equipment for the trip include: cooking utensils, tents, sleeping bags, blankets, waterproof tarpaulins, and some camping tools such as knives, axes, lights … “The items are synchronous, the same style is Vintage Americana (American classic), but each member will have variations. Like me the Vintage Military style (military classic) with US WW2 tent (American tent However, most of the items dating back to the 1930s – 1970s, have the same design and materials to create a unified whole, “Nhat said. Vintage Camping has many limitations because it does not have the support of modern equipment, needs proficiency skills, as well as physical requirements. However, the trip offers an unforgettable experience. Spent two days without phone waves, no noise or dust pollution, Nhat said: “Camping like this helps to feel more with nature. We can watch more and more carefully because we often camp. Two days or more. Fun activities like spring bath, cooking, night star viewing, or regional botanical exploration. This type of picnic is quite new in Vietnam. “If young people want to join, we should camp in close and safe places first to gain experience. We also go for many years before we dare to go,” said Nhat. He added: “Vintage Camping is for those who are really passionate because they have to spend time researching and understanding each item, the amount of money to own them is not cheap.”

Vernon sent a picture of himself wearing a mask, leaving only his nose to breathe. While the guy asked a very casual question: “Isn’t wearing a mask like this right, everyone?” The combination of both the brothers and the fans were on fire, not knowing how Vernon could put on such a mask while typing a message without a word. Vernon asked one, and the brothers answered. The chat is posted attached caption challenge: “The challenge?” The guy’s was officially launched challenge .

Recently, an investment of over $ 200 million has been made to build a mine in the US. This trend is increasing rapidly in North America, according to CoinShares chief strategy officer Meltem Demirors. In March, the US state of Kentucky also passed two bills to reduce taxes for cryptocurrency miners, in order to attract more local workers. With capital released, the construction of a large-scale Bitcoin mining industry in North America has never been so explosive. What happened? China now accounts for 65% of the global Bitcoin mining size, compared with just 7.24% for the US. The exact number may not be the same according to reports from the US and China, but the fact is that the US is far behind on this front. China accounts for 65% of the total global Bitcoin mining capacity (source: Cambridge University) In the early days of cryptocurrencies, American miners were still wondering if their hashrate was paid when contributing to the mining pool. In many cases, miners are paid less than their efforts. Since Bitcoin uses proof of work (PoW), the hash rate becomes what determines what percentage of the miner’s effort is paid off. Proof-of-Work ̣ (PoW) is a consensus algorithm created in the blockchain network, used to validate transactions and produce new blocks in the chain. Meanwhile, hash rate is a measure of the algorithmic ability of a cryptocurrency miner like Bitcoin. Because bitcoin mining involves solving algorithms to confirm transactions, it requires powerful equipment to help find the required hash in the shortest amount of time. But China started to exploit very quickly thanks to cheap labor and electricity prices without having to worry too much about external problems. The country currently leads the world, accounting for about 30% of hydroelectricity and 50% of its coal-fired power generation capacity. The problem of the environment In North America, any act of harmful to the environment is put on the radar of the activists. When the virtual currency craze exploded, Bitcoin mining, which consumes electricity and emits greenhouse gases, quickly became the focus of criticism. Meanwhile, electricity consumption for Bitcoin mining in China will peak at 296.59 TWh by 2024, according to Nature Communications. This exceeds total energy consumption in 2016 by Italy and Saudi Arabia combined. In March, the Bank of America criticized the consumption of one Bitcoin at a price of $ 50,000 for carbon emissions equivalent to 270 tons, equivalent to the internal combustion engines of 60 cars. The PoW mechanism causes Bitcoin transactions to require miners to compete for an algorithm to validate the block on the chain. In return, they are rewarded with Bitcoins for completing difficult problems. So, machines like the ASIC are specifically designed to do this, and they consume tremendous amounts of power. This is actually a security enhancement of PoW, not a bug. If the answers called hashes are too easy to solve, the blockchain network is vulnerable to attack by hackers. However, using a lot of energy isn’t necessarily a bad thing. A company called Crusoe Energy has developed technology to “capture” gas in the central atmosphere at oil wells and use it to power on-site data centers. The company deployed projects in Colorado, Montana, Wyoming, and North Dakota and resulted in a 72% reduction in CO2 emissions compared to burning it. Bitcoin mining is essentially power consuming because it runs 24/7 and needs stable and constant energy sources. Another advantage of Bitcoin is that it uses energy in places far from residential, like mining mines located in remote areas in Xinjiang, China. The big problem today is that Bitcoin is still using fossil fuels and enrich these companies. Only 39% of total energy consumption comes from renewable sources such as wind, water, and solar, according to research from Cambridge University. But even if Bitcoin mining runs entirely on renewable energy, it will create increasing demand for ASICs and disrupt the global supply chain of semiconductors. The end result is a pile of electronic waste that no single green energy source can deal with. The problem could be under control if the industry’s focus was shifted from China to the US, where environmental activists play an active role in curbing energy consumption and carbon emissions. school. Security risks? Aside from the environment, another danger lies in Bitcoin’s consensus mechanism with more than half of the network hashes located in China. That makes it possible for China to control the protocol and reverse transactions. This is a disgrace to Americans when the Internet revolution was initiated in the country of chess, but in the age of cryptocurrencies, China is in control of the game. Cryptocurrency attacks, known as 51% attacks, target a weakness in PoW’s consensus mechanism when a group of people has more than 50% of their hash power. In such attacks, the attacker does not actually steal the virtual currency, but just spends twice the amount he has by executing two transactions simultaneously to two different wallets and defrauding the system. But any exchange with good liquidity can prevent such an attack by setting a withdrawal limit. In the future, the competition of semiconductor chip factories creating more 4.0 shovels is expected to help this industry have global coverage. The end of PoW? Will the PoW mechanism be out of date? After all, Ethereum is emerging with the second largest market cap, preparing to move to a Proof-of-Stake mechanism that significantly reduces energy consumption and speeds up transactions. This mechanism makes it possible for one person to mine or validate block transactions by depositing virtual money into the network. This deposit is locked and returned to its owner after a set period of time, to prevent fraud. Even so, PoW in the 12 years of its existence has demonstrated its ability to prevent any cyberattacks. Meanwhile, PoS still needs time to experiment. Ethereum’s PoS transition phase, which is known as ETH 2.0, was planned 2 years ago and is expected to begin rolling out next July. The new hub of Bitcoin? Neither the US nor China, other emerging countries could soon outperform both thanks to more renewable energy and cheaper operating costs like India. America is thriving, but the gold mines in China cannot disappear overnight unless there are special government regulations. Experts expect that China can drop to 40-50% of the total hash rate within the next three years, and then North America could account for 30%, 20% from Europe and the remaining 10%. scattered in other areas. The problem with the US is that the federal government does not interfere and needs its own policies in states to attract and retain blockchain companies, as is the case with the state of Zug in Switzerland, which is known as the Valley. virtual money of the world thanks to specific policies of the state government. A miner is cleaning the ASIC Several states like Kentucky, Texas, and US cities like Miami are slowly recognizing blockchain as the technology of the future, and experts expect North America to win 10% of the global hashrate next year. Even so, as Bitcoin continues to receive investment, environmental issues will continue to be a major hurdle preventing the explosion of mining pools in North America, said the Hashrate Index expert Ethan Vera. The power failure in Xinjiang on April 16 affected the mines there and indirectly caused Bitcoin to lose 21% of its value from the peak of $ 64,000, possibly the strongest warning to the United States. in the war of cryptocurrencies, the future of humanity.

On Saturday night (23:30 on April 24), Chelsea started the sprint period with a heavy schedule, starting with the London derby at home West Ham. Chelsea entered the final month of the 2020-21 season fiercely, starting with a derby with West Ham Both have the same 55 points, and Chelsea are on top thanks to the sub-index. The London Stadium match will have a great influence on both opponents’ ambitions to win the Champions League next season. West Ham is having a wonderful season with coach David Moyes. Meanwhile, with Thomas Tuchel’s Chelsea, the end of the Premier League race in the top 4 can be considered a success. After the London derby, Chelsea had to fly to Spain to play Real Madrid, within the first leg of the Champions League semi-final. The second leg between the two teams took place a week later, at Stamford Bridge. Between two strong letters with Real Madrid, Chelsea has a match against Fulham – opponents are struggling to stay relegated. Thus, in the next 10 days, Chelsea will face important turning points in both the Premier League and the Champions League. Not stopping, right after completing the semi-finals of the Champions League, Chelsea had to play Man City. If nothing unusual, this match could name Pep Guardiola’s army as English football champions. Real Madrid is Chelsea’s biggest rival Chelsea probably didn’t want to see this. Just trying to stop Man City from winning early, Tuchel teachers and students have a different derby with Arsenal. In the last two rounds of the Premier League, the Blues faced Leicester and Aston Villa respectively – who could completely make them embrace their hatred in their attempt to win the top 4. Also, in mid-May, Chelsea played the FA Cup final against Leicester. 9 battles in a month, density 3 days / match, the sprint to the finish of the Blues is really tough. The challenge with Tuchel Since being selected to replace Frank Lampard, coach Thomas Tuchel has made a big mark with Chelsea. Chelsea’s defense is great Former captain Dortmund and PSG bring a flourishing image for Chelsea to step up in the Premier rankings. They reached the FA Cup final, and the Champions League semi-final. Chelsea spent 20 official matches with Tuchel, with 65% victory. This rate is much higher than its predecessor Lampard – 52.4%. The strength that Tuchel brings is defensive performance. Chelsea only received 9 goals, with 15 matches kept clean sheets. Since Tuchel’s debut at Chelsea, with Wolves 0-0, no team in the 5 major leagues (Spain, England, Italy, Germany and France) has such a high clean sheet rate. However, the attacking effectiveness of the Blues is not high. Only 26 goals were scored after 20 games that Tuchel directed. 1/4 of the past games they cannot score. Great challenge awaits Thomas Tuchel The German strategist helps Timo Werner to be more involved in the match. Kai Havertz also improved. But the mutation is still low. Upcoming, Chelsea’s opponents are all strong teams, or “dark horses” of the season. In the Champions League arena, Real Madrid is much more brave than Atletico or Porto. Domestically, Chelsea won only West Ham 2 in the last 7 matches; inferior to Man City (won 2, lost 4 – including penalty shootout); won only 1 match in 6 recent confrontations with Leicester (3 matches not scored). The past 20 games are just the beginning of Thomas Tuchel’s adventure with Chelsea. Big challenges really await this 47-year-old military leader.

Possessing the strength of vocals and charismatic performance on stage, Song Tung always maintain its performance through each round of the competition. BigDaddy’s student – Emily was said to have a subtle way of handling beyond the age that admired the coaches and judges. On the eve of the night of deciding and announcing the winner, Coach Emily shared feelings and evaluated the outstanding progress of the students at the music race this year. – Hi Emily, how do you feel about Song Tung’s progress after joining GHVN New Generation 2021? – Starting point, Song Tung has a good voice, capable of performing and impressive charisma on stage. After the competition at GHVN New Generation , you have progressed and you are much better. BigDaddy and I have focused on teaching Song Tung what he did not know, such as Rap performance. Song Tung learned and grasped quickly. After difficult challenges from 2 coaches, the way the baby moves is more and more firm and fluent. Moreover, the baby’s dancing ability is also improved. These will be valuable experiences to help you go further on the path of developing a singing career. During the training process with Song Tung, besides the musical ability recognized by the judges, what was the most impressive thing about the student that impressed Emily the most? – I am impressed by Song Tung’s gentle, innocent, obedient personality. After the contest, we often go out with the baby to have the opportunity to talk and get to know each other better. – Before the Finals, what special preparations did BigFamily have for Song Tung? – BigDaddy and I still follow the criteria of Song Tung to what his child loves so that he can complete the exam in the most comfortable way, without forcing him to follow any framework. Song Tung likes to show off his vocals, so we chose a Pop song with a difficult technique to challenge the students. A song composed by musician Pham Thanh Ha will be BigFamily’s choice for the duet competition with the coach. Through this song, we want to affirm that, no matter what, all BigDaddy team members – Emily is still a family, loving and accompanying together. – Observing the performance of the Top 4 contestants GHVN New Generation 2021, how does Emily comment on the children? – All contestants can enter Final They are all very talented individuals, this is also proven by the maturity of the children throughout the competition. Regardless of the outcome, I believe the kids also had valuable joys, experiences and valuable growth lessons at this year’s program. – After sitting in the hot seat with the Kidneeland and MimiMama team, how does BigFamily feel about the other 2 coaches? – Compared with two friends, BigFamily is still “incapable”. The first time BigDaddy and I take on the coaching role of a music contest for child talents, so the confusion and clumsiness are inevitable. However, I believe, the energy that we have brought is definitely not inferior to the two other teams. Each coaching team has its own style and direction, but we are always learning through each other to improve. – Over 14 episodes of TV broadcasts with BigDaddy on hot seats, what did Emily say about this collaboration with her husband? – It was a really enjoyable experience for both of us. Emily and BigDaddy have found new inspirations, feelings and have more experience working with children, … thanks to the process of accompanying the children. – What memories with BigFamily’s small family at the program reminded Emily the most? – It is difficult to choose a specific memory because there are always stories that help me better understand children. Each child brings a unique color and that uniqueness has created a big family “unique” throughout the competition. – Looking back on the recent journey with students and coaches, is there any regrets about Emily? – I feel satisfied and satisfied because I really did my best in this year’s competition. BigFamily brought new songs written by us and our team. Besides, the time and opportunity to interact to understand the contestants on the team can be said to be the biggest success of me and BigDaddy. No matter the results, BigFamily is always proud of what we have at the show. – Why did the BigFamily team choose the “affordable” direction for students to perform songs that are not too challenging? – We always think that choosing the right song will bring success to the kids more than challenge them. The audience can completely recognize the youthful, meaningful music color in the spirit of “big family” through the way we choose songs for each student. – What lessons for herself that Emily learned from the role of coach GHVN New Generation 2021? – Journeys GHVN New Generation 2021 gives me a lot of meaning. Although my experience as a coach is not too long, it has given me new directions in the future. I thought, if I stopped singing, I would become a teacher in the music field. This also needs me to be more cultivated and psychological when working with young children.

Break boundaries in Internet access Elon Musk’s project of covering the Internet around the Earth has begun for users to sign up for testing. You can be one of the first to use this service even while living in Vietnam. Starlink’s ambition is to use 12,000 low-end satellites to cover the Internet to every corner of the globe. So far, this project has been successful in covering all over the Americas with a total of 1,261 satellites in orbit. The billionaire Elon Musk’s satellite Internet project also targets Vietnamese users. Currently, Starlink started allowing users to pre-order to use the service. Accordingly, when accessing the website of Starlink, users can easily choose familiar cities of Vietnam such as Hanoi, Ho Chi Minh City, Hue, Da Nang, Hai Phong, Can Tho … to register for history. use this service. Startlink will start providing satellite Internet services to users in Vietnam in 2022. However, to be one of the first users, users have to pay a fee of 99 USD (about 2.3 million VND) to “book”. Payment will be made via international cards such as VISA, Master Card. The kit offered will include a Starlink satellite pan, WiFi router, power supply, cable, and rack. In case of change of mind, Starlink will refund the deposit to the user. Assoc.Prof.Dr Pham Anh Tuan, Director of the Vietnam Space Center, said that Starlink is a satellite constellation project, in which thousands of small satellites are launched into low Earth orbit (abbreviated as LEO – Low Earth Orbit), located 550km from the ground. Internet signals will be shot from satellites straight down to receivers on the ground, then these devices will broadcast the signal through the local system or directly via wires connected to the customer’s Starlink router. The strength of satellite Internet is breaking down distance limits. Hilly areas, islands, complicated difficult terrain … still have simple internet access Satellite Internet works similarly to cable Internet, except that the system has more moving elements. When the customer accesses, the data request will be transferred from the computer to a satellite internet pan. This pan will broadcast a data request to a satellite orbiting the Earth. At this point, the satellite will send the received request to the ISP. The data is transmitted from the carrier to the satellite, then from the satellite to the satellite Internet pan, down to your router and into the computer. The more satellites, the more stable the signal. These satellites act like base stations, except that they are not obstructed by topographic space. Competition between suppliers According to Assoc.Prof. Dr. Pham Anh Tuan, the appearance of the SpaceX provider will create fierce competition from today’s telecom businesses. However, the bigger problem is that we do not have legal bases to manage cybersecurity for foreign suppliers. Therefore, in the coming time, there will be a need to consider legal frameworks to manage network information security, avoid bad and negative information, affecting socio-economic security. Assoc.Prof.Dr. Nguyen Huu Thanh, Director of the Institute of Electronics and Telecommunications, Hanoi University of Technology, this technology will create a big competition with network operators. Currently, Vietnam’s Internet is also relatively good, has coverage in remote areas, islands, but not as flexible as satellite Internet. Starlink is faster than optical fiber depending on the provider, but it is known that the bandwidth of the satellite Internet is very large, so it will compete greatly with current providers. The important point to compete here is the fee charged by the satellite internet provider, if it is too high, it will also be difficult to attract users. According to Assoc.Prof. Dr. Nguyen Huu Thanh, when the entire Starlink satellite system is put into orbit, this service will provide almost global coverage to populated areas. Users using the service only need to buy a pan to catch the waves, like a pan to watch TV. As for cybersecurity, if we talk about hacker intrusions and users, each person must be equipped with tools to protect themselves. Therefore, this problem is the same as with Vietnamese carriers only. The most important thing is to have fair competition policies, otherwise this market will be lost to foreign hands According to experts, Starlink can have coverage to the country or not depending on the country’s regulations. Currently, many countries have allowed Starlink to operate, but China and Russia will require the service to comply with special rules if they allow Starlink to broadcast on their own frequencies. Some countries prohibit the purchase, sale and use of ground-mounted Starlink receivers. In Vietnam, to manage satellite Internet, it is necessary to soon have appropriate regulations. In terms of feasibility, the cost of Internet services from the orbital satellite cluster is as low as that of Starlink is still 7-8 times higher than the price of fixed broadband Internet service in Vietnam. In the case of being deployed in Vietnam, satellite Internet service will be the solution to the problem of Internet coverage in areas with divided terrain such as hills, islands … In addition, the provision of satellite Internet services using low-orbit satellite beam technology promotes the development of the maritime and aviation industries.

Meanwhile, the way of making “Vietnamized” pancakes when stir-frying seafood of the team of “culinary angels” received a compliment from the chef. In this round, Dieu Nhi – Trinh Thang Binh quickly used 2 pans (one on the stove, one upside down) to ensure the perfect flip. This makes the chef also have to say “extremely brilliant” because the creativity causes “traumatic” on viewers. Dieu Nhi affirms that this is a useful pocket “secret” for “rookie” in the village “hates the kitchen but has to pretend to love”. Hyojung and Seunghee of OH MY GIRL The final product satisfied both teams, but unexpectedly won Dieu Nhi – Trinh Thang Binh. According to chef Park Joonwoo, the Vietnamese stars have tasted better, crunchy standard. Meanwhile, the two OH MY GIRL girls poured the dough too thick to make the cake unevenly. “The taste of the two siblings’ pancakes is like traditional Korean pancake, I was surprised but also a little embarrassed because this is my country’s dish” – Seunghee shared. Back to the kitchen in Vietnam, Dieu Nhi and Trinh Thang Binh had to bring Korean pancakes to the Vietnamese kitchen, and at the same time rework this dish with the correct recipe conveyed by chef Park Junwoo. Both cook with two guests Kaity Nguyen and ST Son Thach. The two teams playing Trinh Thang Binh – Kaity Nguyen and Dieu Nhi – ST Son Thach had to participate in the side game “three stars to lose” to gain the advantage of taking raw materials 30 seconds before. Kaity Nguyen is adorable when playing games The “misconduct” of ST and Dieu Nhi not only gave the pair less time to get the ingredients, but had to stand for more than 30 seconds in the ice pool. While the team was almost done with the challenge, Team Dieu Nhi was still lying on the floor because they couldn’t stand the cold feeling of the penalty. Team Dieu Nhi continues to “play comedy” with a series of funny moments After that, each team has 30 minutes into the kitchen to complete the Korean pancake. Although she did not have much experience in cooking Asian food, Kaity Nguyen was calm and became a “bearer.” team “For Trinh Thang Binh. She does the manipulations according to memory one by one, while Trinh Thang Binh advises on spices and reminds the ingredients needed for the cake to harmonize the flavor. In the kitchen of Dieu Nhi – ST Son Thach is again bustling and there are many situations “laughing to tears”. Being a person who is not good at the kitchen, and the part does not understand each other, both ST Son Thach and Dieu Nhi expressed embarrassment. Besides, MC Dai Nghia’s one-handed cooking challenge continues to make it difficult for the stars. The teams gathered to make Korean pancakes After 30 minutes in the kitchen, the two teams finished the required Korean pancakes. From the outside, they are “delicious”, but according to the Korean chef, the dishes of Trinh Thang Binh – Kaity Nguyen team are cooked evenly, the skin is crispy and the taste is better than the other team. In the end, Trinh Thang Binh – Kaity Nguyen won. Volume 2 Eat It Then Tell In the end, Vietnamese audiences have one more choice when it comes to Korean cuisine. With easy-to-find ingredients and simple cooking methods, Korean pancakes can be made at home. Episode 2 Eat, Then Tell

Chinese fleets are lined up at the Ba Dau Rock area in the South China Sea. Photo: CNN

Two weeks later, more than 40 Chinese ships remained in the Ba Dau Stone and the statements became more concise. The Philippine Foreign Ministry on April 12 warned China that Manila would issue daily protest diplomatic notes as long as the mainland’s “marine militia” remained in the area. The Philippines authorities have used a phrase similar to the US way of describing the Chinese fleet.

Bloomberg quoted Carl Schuster, former director of missions at the US Pacific Command’s Joint Intelligence Center as commenting: “If your goal is to capture an ocean and atoll, without fighting, this is an excellent dishonesty tactic. Only professional seafarers knew it was a lie. No one allowed their ships to ‘shelter’ in the hurricane zone several weeks before a storm. If they were really commercial ships, it would cost hundreds, if not thousands, of dollars a day to lay these ships idle side by side.

Analysts Andreo Calonzo and Philip Heijmans said Beijing appears to be probing whether the new US President Joe Biden will take any action after pledging to shake hands with allies in the region to prevent Chinese assertiveness or not. Philippine Foreign Minister Teodoro Locsin blamed the Obama administration for failing to stop Beijing in a similar incident in 2012 at Scarborough Shoal.

“This is a test of what the Biden administration is willing to do. The way the US responds will determine the next challenge. For now, everything we (the US) have done is more eloquent than substantive, ”said Schuster, currently professor in military science and diplomacy at the University of Hawaii Pacific. emphasize.

Complex decisions

Last month, the US vowed to stand with the Philippines while accusing China of using “maritime militias to intimidate, provoke and intimidate other countries”. When asked about relations with China at a news conference the same month, President Biden revealed that his administration “would hold China accountable for obeying the rules” in the South China Sea and elsewhere.

Another big problem is how to correct the response. China’s use of commercial fishing vessels resembles a “gray zone” tactic, allowing Beijing to deny that anything is wrong. Sending an aircraft carrier or other warships near the reef risks becoming an overreact, making the United States seem like the aggressor.

On the contrary, doing nothing can give the impression of weakness. Over the past few years, the United States has increased its challenge of China’s sovereignty over the waters, increasing the frequency of free navigation operations around disputed territories. The Biden administration also reaffirmed that the US-Philippines defense treaty covers every attack in the South China Sea, which was made clear under former President Donald Trump after decades of ambiguity.

Another major problem for Mr. Biden is Philippine leader Rodrigo Duterte, who has weakened the alliance while praising closer ties with Beijing.

According to Rommel Ong, a retired Philippine Navy admiral and now professor at the Ateneo de Manila University School of Management, under President Duterte there will be only very limited options for the Navy. Manila’s response is believed to be limited to sending objectionable diplomatic notes and anti-China statements via social media.

The Philippines’ statement on April 12 used some of the strongest words, including a 2016 international arbitral tribunal ruling. The statement also condemns the Chinese Embassy for criticizing the minister. Defense Delfin Lorenzana, who last weekend said the weather was fine and boats had no reason to stay in the Ba Dau Rock area.

Warning

Duterte’s government responded to China’s April 3 statement with a statement that it hopes Filipino officials will “avoid any unprofessional remarks that may add to irrational feelings”. . On April 13, Chinese Foreign Ministry spokesman Zhao Lap Kien accused the Philippines of violating the United Nations Charter, the Law of the Sea and international law by invoking the 2016 ruling of the United Nations court. But Beijing insisted on rejecting.

Mr. Trieu warned the Philippines should see the situation “objectively and properly, stop exaggerating the problem to avoid any negative effects on the bilateral relationship between the two countries, stability and peace in the country.
