After interim analysis CureVac defends its vaccine

Status: 06/18/2021 10:19 a.m.

Although an interim analysis of the CureVac vaccine only showed an effectiveness of 47 percent, company boss Haas does not want to know anything about a failure. He is hoping for further tests so that the vaccine will be ready for the market after all. The negative news for the Tübingen company CureVac continues. At first, the company lagged behind the competition in developing its corona vaccine. Then the company went late to the crucial phase 3 to test its vaccine – at that time there were already several variants of the coronavirus. The next bad news followed yesterday: CureVac announced in a mandatory stock market announcement that, according to an interim analysis, its corona vaccine had a preliminary effectiveness of 47 percent against Covid 19 disease “of any severity” have. The value is significantly higher for the other preparations approved in the EU.

“Wild type hardly plays a role anymore”

Company boss Franz-Werner Haas has now gone on the offensive. He defended the company’s corona vaccine against the dpa news agency. No other vaccine has been tested on so many virus variants, he said.

“In fact, it is actually not correct to compare the number of the provisional effectiveness of our corona vaccine and the numbers of the effectiveness of other vaccines”said Haas. The study on the corona vaccine candidate CVnCov contained 29 virus variants. The original virus, the wild type, hardly plays a role anymore. “The efficacy figures for the other vaccines would probably look different if their studies had been carried out at a later date.”

Degree in three weeks

The Tübingen-based company would like to complete the analysis of the data from the final study phase in the next two to three weeks. Haas was convinced that the effectiveness of the vaccine would change again. As soon as this has been completed, CureVac will advise the EMA as to whether further data is required.

The company remains convinced that it will bring its vaccine to approval. According to Haas, even a possibly relatively low effectiveness should not stand in the way. “In view of the pandemic, it can only be said: If there is an effective vaccine, it should also be used.” Haas also referred to the numerous developing countries in which little or no corona vaccines are currently available. The scientific director of the vaccine study at CureVac, Peter Kremsner, believes that it will certainly be possible to make the vaccine operational. In an interview with the BR he said: “That will work for sure. From my point of view, this will not be possible in the next few weeks. But it will be possible to prepare the vaccine so that it can be very effective.”

“It was a noble cause”

The SPD health expert Karl Lauterbach estimates that the setback when entering the market will contribute to the vaccination campaign losing pace for two to three weeks. The promise of the federal government to make a vaccination offer to all adults by the end of the summer is not at risk. “We will reach herd immunity in mid-September”said Lauterbach in the daily topics .

Lauterbach pointed out that the CureVac serum is the “noble” I wanted to be a cheap and very effective vaccine. It would have been predestined for poorer countries. The EU had promised 400 million doses of CureVac to poorer countries. Lauterbach assessed it as a tragedy that this delivery has now been canceled.

No withdrawal of the investor

The announcement of the preliminary effectiveness had caused a drastic plunge in the stock exchange price of CureVac. Investor Dietmar Hopp still believes in the company. He will definitely stay as an investor, he said “Munich Mercury”. He is a firm believer in the company.

The federal government is also holding on to its stake in CureVac, as the Ministry of Economic Affairs said. Last year, he entered CureVac through the KfW development bank with 300 million euros and, according to KfW, holds a share of 16 percent. The federal government has no influence on the operational business, explained the ministry spokeswoman

In summary, the vehicle is running at a higher speed, and the driver starts to depress the brake pedal with a lighter force. After that, the automatic emergency braking function is activated and has a function, which improves the braking force and reduces the impact of the collision. The driving system is normally involved in the work and reduces the speed of the car. According to data released by Tesla, Tencent Technology is authorized to sort out the opinions of users.

Opinion 1: Tesla has a situation where it selectively releases data that is beneficial to its own side The data disclosed by Tesla through the media is incomplete and cannot give a clear conclusion on the cause of the accident. Tesla has more detailed and richer data, but it has not announced it. There is a suspicion that selective publication of the published data is beneficial to oneself. Zhihu user Shi Gaoba believes that data such as the data of the brake pedal depth sensor is selectively not released by Tesla. The braking process requires the participation of multiple systems, including at least the brake pedal switch sensor, pedal depth sensor, motor, vehicle controller, ESP system (including ABS), the activation of AEB emergency braking, and the participation of forward radar. As a result, only a few seemingly professional data such as vehicle speed, pedal switch signal, and brake cylinder pressure were given. The pedal depth data, motor speed signal, and forward radar data are all given to completely restore the process of the car owner’s braking, motor speed and vehicle speed verification, and forward radar to see the distance of the vehicle ahead. The data of the brake pedal depth sensor can truly reflect whether the owner has stepped on the pedal violently, and whether the pedal cannot be stepped on due to the increased resistance of the pedal. Tesla said that the driver stepped on the brake pedal, but did not release the data. Zhihu user Mr. He said that Tesla has more abundant data, but Tesla has not disclosed it publicly. Currently, only Tesla is equipped with an EDR (Event Data Recorder) data recorder, which can be understood as a black box. The measurement frequency of the data recorded by the black box EDR is currently unknown, only Tesla employees. But the amount of data measured is definitely detailed, borrow a picture: As can be seen from this figure, the key information recorded by Tesla’s EDR is: Vehicle speed; odometer; camera data, braking and acceleration data, short video clips of accidents, safety system data, etc. If you want to analyze what happened when the accident happened, I think some key information is needed: Collision sensor signal: can know the time of the collision Brake signal: It is not only necessary to know whether the brake is pressed, but also to know the stroke of the brake pedal (how much the brake is pressed). Brake cylinder pressure signal: can know whether the brake cylinder provides boost Accelerator pedal signal: Including the degree of opening, you can know if the accelerator was stepped on before and after the accident Speed ​​signal: can know the current speed ABS/esp signal: can know whether ABS is activated and whether esp is activated or not Motor status: including motor speed, quadrant, motor torque, etc., to see if the motor is still providing driving force when the brake is stepped on. ibooster status: able to know the distribution of braking torque. Vehicle failure information: whether there is a failure Note that the above data requires raw sensor data. Taking the brake pedal as an example, in addition to knowing the final opening signal, you also need to know the most original voltage signal. The voltage signal is the true sensor value. Viewpoint 2: Sufficient braking measures have been given According to Tesla, the vehicle is traveling at a higher speed, and the driver starts to depress the brake pedal lightly. After that, the automatic emergency braking function is activated and works, increasing the braking force and reducing the impact of the collision. , The braking system is normally involved in the work and reduces the speed of the car. Zhihu users questioned this statement, believing that the driver depresses the brake pedal in 23.17 seconds and triggers abs in 25.74 seconds, and sufficient braking measures have been taken. The following are the views of Zhihu user Kang Jianmao: It can be seen from the data that the driver depresses the brake pedal from 23.17 seconds, the pressure of the master cylinder gradually increases, and then triggers abs at 25.74 seconds (at this time aeb does not start, indicating that the driver has already done so without the help of aeb The maximum deceleration capacity of the vehicle was reached by stepping on the brakes), and then the pressure of the master cylinder continued to rise, until it reached the peak value in 27.63 seconds (maybe aeb, or it may be a miracle of the owner’s life and death). However, Tesla’s own text stated that within 2.7 seconds of stepping on the brake, the pressure of the master brake cylinder was only 45.9 bar. Please, did you step on the abs at that time? What does it mean? How many people can step on abs when driving? Then Tesla himself said that the brake pressure gradually increased to more than 90 afterwards. Anyone who knows a car knows that once the ABS is started, it has basically reached the maximum braking capacity of the vehicle, and then it will not work if it is stepped on. Tesla also said that aeb played a role and successfully helped slow down, excuse me? This wave of data actually proved that the driver stepped on the brake hard enough. After all, it was the abs that was stepped on by others. Then even if the aeb system intervened, it did not help to decelerate. If you can’t stop it, you can’t stop it. Viewpoint 3: Deceleration is 0.6g, the braking ability given by Tesla cars is not enough Under normal circumstances, the braking of a family car is 1g, but Tesla’s ABS trigger condition is only 0.6g, which is lower than that of a normal family car. The following are the views of Zhihu user Kang Jianmao: According to the data given by Tesla itself, from a speed of 94 in 25.41 seconds to a speed of 48.5 in 27.45 seconds, the vehicle speed dropped by 45.5 kilometers per hour when the ABS was triggered in 2 seconds (that is, full braking). The total is 12.63 meters per second, and the average acceleration is 6.3 meters per second. This braking ability really proves that Tesla can’t stop. The ABS is only about 0.63g, and the normal family car is close to 1g. The following are the views of Zhihu user cao sir: Dare the driver lightly step on the brake to trigger ABS, but hardly stepping on the brake is not enough to trigger ABS. Is this logical?

The entrance to the young girl’s beautiful little house is covered with wild flowers with a rustic beauty. “If you fail, go home” Early in the morning, Tran Phuong (25 years old, Hai Phong) woke up when the morning light spread the brilliant sunlight on the daffodils with sparkling dew. Making a cup of coffee, she came to sit at the corner of the house designed by herself to watch the sunrise before rolling up her sleeves to water the flowers. After the small path full of wild flowers, the young girl’s garden also has many kinds of precious, beautiful and unique flowers. More than 2 years ago, Phuong left the city to the suburbs to find peace for her soul after her failures in life. The girl has turned her old place into a beautiful little house in the “forest” of colorful flowers. Phuong said: “At the age of 23, I failed in everything, including love. People say that they fail to go home. When we are under pressure from work and life, we all want to go home or run far away from the city to find our own silence, and I did that. Phuong’s small house was designed by his own hands to design and renovate in the “forest” of flowers and plants. “My house is in the suburbs so there is a vacant land. I have renovated it to my liking. I renovated the old house into a nice little house, making a list of plants suitable for the garden and climate. After about 1 year, I have a garden with many kinds of flowers and fruits, ”added the girl. The girl turned the land with only wild flowers into a “forest” of flowers with many green trees interwoven with flowers such as hydrangeas, my tea, chrysanthemum … Phuong said that she loves wild flowers because they have a rustic beauty and are associated with her childhood. When she was a child, Phuong still picked wild flowers for her mother. Therefore, when designing the garden, she always leaves the wild flowers and takes care of them like the flower stump that she collected and planted. Because her mother likes roses, the girl decided to plant many of these flowers in the garden. The entrance to Phuong’s beautiful little house is covered with purple sea lilies, white wild chrysanthemums and brilliant yellow flower vines that even she does not know the name of. Inside that small path is the blooming place of many types of hydrangeas, narcissus, myrtle tea, chrysanthemum, rich precious, wisteria, wisteria … Phuong said roses make up 60% of her flower area. Her mother is the one who instructs Phuong to take care of her flower garden. Phuong loves flowers so much that, whenever she sees any beautiful plants, she immediately buys them and asks for seeds to plant. She even collects unnamed flowers from the forest to plant and take care of in the garden. The girl said, in the past, more than 200 square meters of her family’s land contained only the old house and confetti bushes. Wisteria bloomed in Phuong’s flower garden. However, after nearly 2 years, Phuong has turned them into a garden filled with flowers with lovely sunrise and sunset views. “During that time, I received joy rather than fatigue. Because, when I make things more beautiful by myself, I feel happier than tired, ”said the girl. Where to find peace for the soul Daffodils bloom white in the morning mist in the early morning. Phuong said that from the day she returned to her hometown, immersed in the plants, she felt love for life, love nature and cherished life more than ever. Now, Phuong can settle herself in order to find peace. She forgot the hustle and bustle in the city to watch the dawn, enjoy the flowers, and reflect on the sunset in the afternoon. Phuong said, she loves to watch the sunset because it is the softest light and color of a long day. In Phuong’s garden, there are also fruit trees that are bearing fruit. Everywhere in the garden makes the viewer feel at peace. Phuong himself supported wood and closed a small corner at home so that he could sit and watch the sunset at the end of the afternoon. In addition to the garden with hundreds of types of flowers, Phuong’s kitchen is also cared for with classical beauty and romance. The small kitchen with a chimney and a wood-walled fireplace is a place for Phuong to create delicious dishes for her mother. This is also a place for family members to gather together. So, she came up with an idea and bought wood herself to design and decorate her style for 4 months. Phuong said that from the day she returned to her hometown, immersed in plants, she felt love for life, love nature and cherished life. Phuong shared: “This is the place to create delicious food for kids who like to cook like me. In addition, on rainy days, I often go to this wood fireplace to watch the rain, read books, listen to the radio … It is a very interesting and peaceful experience ”. The kitchen is built of wood with a chimney, a classical fireplace designed by the girl’s hand. Phuong often comes to sit by the fireplace watching the rain, listen to the radio, read books and make delicious food for her mother. After 2 years of returning to her hometown and being immersed in nature, the young girl said she had found a “smile”. That is the smile of his family members and even Phuong himself. She quickly healed the wound of her heart after her first failures. “Now, I have found a smile. Safe smile, “the young girl shared. Now, Phuong’s joy in the day is taking care of the flower garden and watching the sunset, which help her clear her soul and find a peaceful smile. Posts: Nguyen Son Image: Phương Caryl

Conversely, if the car owner chooses to match the color of the car, it will often affect the mood. Vehicle owners often have bad luck on the road, easily irritable and frustrating, when riding a car must spend money to repair, if there is an accident, it often has worse consequences than fateful cars. What color was the age of the Goat born in 1979? People born in the year of the goat in 1979 belonged to the destiny of Fire. So the choice of car color for people born in 1979 must also be based on destiny. People born in the year of the goat in 1979 belonged to the destiny of Fire. So the choice of car color for people born in 1979 must also be based on destiny. What color car is the Age of the Goat 1979? Specifically, people born in 1979 are the following: – Red, pink, purple: these 3 colors represent the destiny of Fire, which is the fate of the age of 1979. If you ride this color, people born in the year of the Goat will be less likely to get lost. At work, life is not too lucky, but not too risky. Those who buy cars for travel (not in business) can choose these colors to balance their lives. – Green: Green represents par Moc. Moc Sinh Hoa is the rule, the car owner is at the age of 1979, so the car will transmit life energy to the owner, help the owner get a lot of luck, and promote his promotion. The owner of Ky Mui car who chooses a car in the color Moc will also move safely, often have good luck, the car has less damage and accidents. For those in the transportation business in 1979, the green car was the most beneficial color. Conversely, people born in 1979, Ky Mui, will be associated with the following colors: – Yellow, brown earth: Yellow, brown earth are the colors representing the Earth system. Hoa Sinh Tho, which means that if the car owner is born in 1979 with the fate of Hoa, if the vehicle is in the color of Earth, it will lose energy and luck. Buying a car to run, the owner of the car is easily irritated, frustrated and tired. Being attracted to luck, the work and life of the owner of the car is also affected, there may be an accident, the wind might have an accident, and affect the life. This is a great color for the owner of Ky Mui’s car. – White, gray, gray: these 3 colors represent Kim par. Kim and Hoa were jealous, but the owner of the vehicle was Ky Mui, Par Hoa. Vehicle and people are different, the car will be damaged, have an accident, and have trouble, costing repair. – Black, blue: These 2 colors represent the fate of Water that is firmly engraved with each other. Just like in the case of a car with the color Kim, the car with the color of Thuy also engraves the owner, so it is very harmful. The owner of the vehicle is susceptible to health problems, and the ride is also unfortunate, requiring a lot of repairs. Ky Mui will merge with green vehicles, according to Moc Hop Moc relationship and will be the best against white, gray, and gray vehicles (Kim Khac Moc). Red car is the fate of people born in 1979 In fact, male / female capital born in the same year often has different personalities, but people born in 1979 Ky Mui have a special feature that is the same destiny. Specifically, both men and women born in 1979 are the same Chan, onion Moc, east, star Tam Bich Tinh, belonging to the East four destiny group. In which, male / female born in 1979 Ky Mui will merge with green car, according to Moc Hop Moc relationship and will be the worst with white and gray cars, record (Kim Khac Moc). How to neutralize car color destiny for people born in 1979 For people born in 1979 Ky Mui, the color of the most cavalry car is white, gray, gray. However, 3 colors occupy a large number of cars on the market and are often also quite affordable prices. Therefore, there are many car owners who know fate but still deliberately choose cars with this color. In fact, choosing a car with age is not irreconcilable. If the car owner has determined to choose the colors of the car to conquer the destiny, there are some simple ways to solve the following colors: – Choosing the car cabin according to the fate color: that is, if the car owner has chosen a car with an incompatible color exterior, the interior of the car must use the fate color. For people aged 1979, you should buy a car with red and green furniture to neutralize. Currently, the market has a lot of models using red and black seats, so maybe this is not a difficult problem for car owners. – Choose a car trim with a fateful color: If you cannot choose a model with an age-appropriate cabin, you may consider choosing decorations with age-appropriate colors. For people born in the year of the Goat, you can choose a piece of green jade or red feng shui statues that also greatly reduces the incompatibility factors due to the car’s exterior color. Ky Mui 1979 should buy a car with red and green interior to neutralize. In the event that the two above methods do not resolve the conflict between people and vehicles, you will have to find the most difficult option, which is to repaint the car to a fateful color. However, this method requires you to spend a large amount of money, in addition, it also affects quite a lot on the original paint color of the car, so it is not recommended much.

Specifically, Kia Seltos in Vietnam is manufactured and distributed by Thaco with a 1.4-liter turbocharged engine, different from the Seltos series equipped with a 2.0L Nu MPI engine recalled because of an engine error in the US. Kia Seltos in Vietnam is equipped with a Kappa 1.4 T-GDi engine, with a capacity of 138 hp and a torque of 242 Nm. Previously, according to an announcement from the US Road Traffic Safety Administration (NHTSA), more than 147,000 Kia Seltos and Souls had technical problems due to the incorrectly manufactured oil ring. standard. This leads to a possible lack of lubricating oil, overheating, locking the cylinders and potentially causing a fire hazard. If the engine is having problems, it will cause the lubricating oil to lose quickly, make strange noises or turn on the oil pressure warning light. Kia North America said it had dealt with the problem with its engine-clutch supplier. In addition, the vehicles in the summoning area will be checked and replaced with damaged parts. In Vietnam, Kia Seltos is an urban SUV that competes with Toyota Corolla Cross, Hyundai Kona, Ford EcoSport, Mazda CX-30, Peugeot 2008 or Honda HR-V.

Hiep Thuan commune (Phuc Tho, Hanoi) is a famous mulberry growing area that specializes in supplying the Hanoi market and the central provinces. According to Mr. Nguyen Van Tuan, Chairman of the Farmers Association of Hiep Thuan commune, “Since ancient times, the elders in the village mainly planted mulberries to raise silkworms. However, before the requirement of reality, mulberries do not bring income, people turn to growing short-term crops such as soybeans, corn to serve daily food. About 30 years ago, taking advantage of favorable soil conditions, people switched to planting mulberry trees for fruit ”. Mulberries produce one crop per year, usually lasting from January to the beginning of April on the lunar calendar. At this time each year, mulberry gardens are in season, the fruit is black, sweet and succulent. However, this year, due to the influence of weather, most of the fields have very few fruits. Many households who lost their money did not want to visit the fields, weeding, and cultivating tree stumps. Ms. Thuy, a mulberry-growing household in Hiep Thuan commune, shared: “This year, due to the influence of salt rain, the strawberry is all hard, dry and white. I planted 3 sao and took up 30% of the area. I should have had no strawberries at home, but many of them abandoned it, didn’t care anymore, but I still came here to pick every broken fruit, re-cultivate each strawberry root, pull the weeds to make the base to try to salvage. beveled, how much is “. The weather has been difficult, the mulberry farmers here are also forced to price when they cannot manage the output for the product. Mainly traders buy small retail locally. At present, the price of mulberry purchased at the garden is only 8,000-10,000 VND / kg. Mr. Hiep (Hiep Thuan commune) shared: “My family has planted 1 sao of mulberry trees for 4-5 years. The most difficult thing about growing this plant is pests and diseases, unpredictable weather and unstable and unstable prices ”. Every strawberry harvest, people gather at the village gate waiting for the small trader to weigh and pick up the goods. If there is a good season, good price, farmers will earn 20-30 million / acre / crop. Although it is a famous mulberry growing area, according to the President of the Farmers Association, the farming method of farmers is only spontaneous. If the price is good, the acreage will be expanded, otherwise it will be cut down to plant other trees. Currently in Hiep Thuan commune, the largest mulberry farmer only reaches 3-4 sao, the rest is only 1-2 sao. “Currently, the locality is also having a policy to restructure crops, including mulberry trees. However, the output of the mulberry tree is a problem. Currently, there are no enterprises and stable purchasing units for people to feel secure in production ”, said Mr. Nguyen Van Tuan, Chairman of Hiep Thuan Commune Farmers Association. Mulberry is a plant grown quite simply. There are households that propagate and graft themselves. After 1 year, from the beginning of planting, it is possible to harvest. From the second year onwards, strawberries will produce more wrong and delicious fruits. After 8-10 years, productivity will gradually decrease. What’s interesting about this perennial crop is that it takes less care. End of mulberry crop, people cut, prune and move to other jobs. At the end of the year, the mulberry tree loses its leaves, then people go to the field to fertilize it so that the tree can produce young leaves to welcome new fruit season. In general, you do not have to care too much, also reduce the labor force somewhat. When the berries are nearly ripe, they will change from green to pink, and ripe fruits will turn red, then crimson. At that time, people will pick strawberries for sale. This fruit can only be harvested manually. During the mulberry season, most people gather in the fields to pick from early morning to dark. According to strawberry growing households, on sunny days, strawberries ripen faster and sweeter than a cold, rainy day. Mulberries can be eaten directly or soaked in sugar as a refreshing drink. Hiep Thuan Strawberry followed traders around Hanoi streets and neighboring localities to reach consumers. And mulberry trees are still trees that bring many economic benefits to the households here./.

“The Air Force had a step back in progress with its supersonic missile program when the first test with a propulsion failed. The B-52H bomber took off on April 5 to launch the prototype AGM-183A, but the test bullet could not complete the launch procedure and was safely hung on the plane until it reached the Edwards base ” . Missile AGM-183A onboard B-52H aircraft. The test was to test the performance of the propulsion engine, as well as the detachability of the supersonic surfacing vehicle after the rocket engine stopped working. The warhead is designed to self-crumble shortly after being separated from the engine, helping to minimize the no-fly zone for ships and aircraft. The US Air Force has conducted seven test flights with the missile model AGM-183A to collect positioning data and flight parameters, test the ability to integrate missiles onto the B-52H launch platform and build procedures. commissioned for the first test shot. The AGM-183A hypersonic missile is also known as the “Aircraft Launched Rapid Reaction Weapon” (ARRW). This is one of the supersonic missile programs being developed for the US Air Force to close the gap in this field with Russian opponents. Especially according to the US Air Force’s statement, the AGM-183A possesses many advantages over the hypersonic missile Kinzhal of the Russian Air Force. The US side said that the parameters on Kinzhal of Russia are equivalent to the AGM-48 Skybolt (developed 60 years ago) of the US and far behind the current AGM-183A. The AGM-183A is superior to the Kh-47M2 Kinzhal in that it does not require the launcher to climb to very high altitudes and maintain Mach 2 as the Kinzhal’s speed and still easily reach design specifications. In particular, according to the US Department of Defense procurement advisor Will Roper, the AGM-183A has an impressive speed when it can reach a maximum of nearly Mach 20. It can be seen that the AGM-183A has a much faster speed than the Kinzhal when the Russian missile reaches just above Mach 10. Although not yet launched, but with the aforementioned parameters, the AGM-183A deserves to be considered a rival to Russia’s supersonic weapons today. But for the AGM-183A to enter service, it may take the Americans a long time. Meanwhile, Russia is ready to equip Kinzhal after successive trials of the weapon.

Made of iron with a simple structure, the lever scale was a very familiar measuring instrument in Vietnam in the early 1990s and earlier. Few people believe that this scale has a very long history. (Photo taken at the Museum of Ho Chi Minh City).

According to Chinese accounts, the balance is an invention by Lu Ban (507 BC – 444 BC), a famous craftsman who lived in the early Lu Kingdom of the Warring States period in Chinese history.

Lu Ban’s lever scale is made of wood, consisting of scales, weights, and scales, operating on the principle of leverage. Based on the Red Dipper and the Lucifer Nam Dau, he engraved 13 engraved lines on the scale, setting 13 taels to equal 1 kilogram.

After the unification of the six countries, Tan Thuy Hoang added three engraved lines corresponding to the three-star “Phuc Loc Tho”, changed from 13 taels to 16 taels equal to 1 pound.

According to the old convention, the marking on the scale must be white or yellow, not be used black, implying that the business must be fair, integrity, not dark.

The first engraved line on the club scale is called the “leveling table”, its position is the hanging point of the weight with the weight hook when the weight is in equilibrium. The most important point when doing balance is that you have to choose the right “goal”.

Despite its simple structure, the balance lever has quite high accuracy, easy to use, not difficult to transport and manipulate. Over time, these scales have added improvements to make them more convenient to use.

From China, the balance was introduced into Vietnam and became the main weighing and measuring tool of the Vietnamese people for many centuries.

The lever scale was widely used until the end of the subsidy period, with its design not changing too much after thousands of years. It used to be an “inseparable” item of housewives across three regions.

Since the Doi Moi period, with the popularity of many modern scales such as clock scales, electronic scales … lever scales are no longer used in life.
