We know that the Wei River, which flows through dozens of cities and counties in Gansu and Shaanxi provinces, is the largest tributary of the Yellow River. It has a total length of 818 kilometers and accommodates approximately 270 large and small rivers. It is one of the oldest rivers in China. This is the birthplace of the ancestors Fuxi and Nuwa in ancient Chinese legends. It is the origin of the first ancestors of the Chinese people, Xuanyuan Huangdi and Shennongyan. Legendary stories such as Emperor Wen’s “Baling Tuomeng” are one of the oldest habitats of the Chinese nation and one of the earliest birthplaces of Chinese culture. But who would have thought that the source of such a mighty Weihe River, which is dwindling thousands of miles day by day, is the three-eyed clear spring hidden in the depths of a mountain named after “birds and mice”? This mountain is the uncommon mountain Niaoshushan, which is known by the Scriptures. This eye spring is the “Pinzi Spring” in the deep forest on the south side of the mountain. Niaoshu Mountain, recorded in the “Shanhai Jing·Xishan Jing” as “Birds and Rats with the Same Cavern Mountain”, is located about 10 kilometers southwest of Weiyuan County, Gansu, and belongs to the remnant of Kunlun Mountains. It is the watershed of the two rivers of Tao and Wei. The birthplace of the Weihe River. There are many historical records about this mountain. For example, in Shangshu·Yugong, it was mentioned that Yu had “guided the Wei from the same cave and the mountain with birds and mice” during the water management. The record of “Niaoshushan in the south of Weiguting in Shouyang County, Longxi Province” and so on. The name is called because there are a lot of birds and rodents in the mountains, and the geographical environment is particularly special. There are no trees for birds to make nests to lay eggs. In order to ensure the safety of their eggs, the birds decided to settle in mice. In the cave, over time, the bird and the mouse are mutually beneficial and coexist in harmony, and there is a scene of “birds and mice in the same cave” that people have seen. In fact, there are many legends about the same cave with birds and mice. It is said that the bird and the mouse were changed by a loving couple. The wife is hardworking and kind, but the husband is lazy. Although the days are poor, he is respectful and respectful. The husband often admires the birds in the sky, being leisurely and free from labor. One day his wife accidentally rescued the Dragon King of the Weihe River by the river. In order to repay her, the Dragon King asked her to go to the opposite mountain when the cock cried the next day. When the appointment was made, the husband was lazy, and when his wife climbed to the top of the mountain. He just arrived at the mountainside, so the Weihe Dragon King gave his wife a pair of wings that could fly into the sky, but the husband only got a pair of sharp teeth for eating wild fruits. The wife can’t forget the husband she loved, so she went to live with her husband in the cave. This is the beautiful legend of the same cave with birds and mice. Since we talked about Niaoshu Mountain, of course we have to talk about the “Pinzi Spring” at the source of the Weihe River hidden deep in the mountain forest. As the name suggests, Pinzi Spring is composed of clear springs with three eyes in the structure of “Ping”, and each spring has very ancient legends. The “Legend Whip Spring” was named after the word “Legend Whip” was written here by the king of Tang. It is said that Li Shimin, Emperor Taizong of Tang Dynasty, passed by here during his western expedition. When drinking water in the spring, he accidentally dropped his whip and disappeared. So he wrote down the word “Legend Whip” by the spring as a mark. “Yu Yangquan” was named because it was called a divine spring by Yu. The Temple of King Yu by the spring was built to commemorate Yu’s governance of the Wei River. When Dayu and the God of Water worked together in a decisive battle here, his soldiers drank the spring when they were tired of people and horses. They felt refreshed and morale. They defeated Gonggong in one fell swoop and won the victory in water control. “Tuyunquan” is said to be the “Dragon Pond” of the Dragon King of the Weihe River. According to legend, someone once saw the Dragon King here spit out smoke and clouds, spreading clouds and rain, and it is said that it rains whenever there is bubbling in the spring. Of course, in addition to the profound historical and cultural background, and the rich cultural landscape, the natural scenery of Niaoshu Mountain is also extremely beautiful. Here, the green hills are like Daisies, the clear waters are like practice, the forests are dense, and the ecology is excellent. If you have the opportunity to go to Gansu, you must take a look.

Trang An Scenic Landscape Complex – an attractive destination of Ninh Binh. Abundant tourism resources As an ancient land located in the Red River Delta, Ninh Binh used to be the capital of Vietnam (in the period 968 – 1010) with 3 dynasties Dinh, Le, and Ly. Traces of the ancient capital preserved intact to this day are the relics of Hoa Lu ancient capital. Along with that is a diverse humanistic tourism resource with more than 1,500 historical – cultural relics, including 1 World Cultural and Natural Heritage, 2 Special National Monuments; 225 festivals and 83 typical traditional craft villages. Referring to Ninh Binh, it must be mentioned that natural resources are extremely rich, typically the Trang An Scenic Landscape Complex which has been recognized by UNESCO as a World Cultural and Natural Heritage with 400 large and small caves. In addition, Ninh Binh also owns the largest forest area compared to other provinces in the Red River Delta (more than 29,000 ha); in which, there is Cuc Phuong National Park – home to nearly 2,000 species of higher plants and 2,600 species of animals. In addition, there are special-use forests of Hoa Lu rocky mountains and Kim Son coastal mangrove forests with many species of animals and plants listed in the World Red Book. The above potentials are the conditions for Ninh Binh to build many types and products of tourism such as spiritual tourism, culture – history, ecology, resort, community, heritage, MICE (combined tourism). As a result, many tourism products of Ninh Binh have been highly appreciated by the international media, such as Tam Coc tourist area, which was introduced by CNN as one of the seven most beautiful caves in Vietnam and a newspaper. Telegraph (UK) once voted as one of 15 “beautiful but little known” places, or Bulletin magazine (Switzerland) voted Ninh Binh as one of the 10 most attractive destinations in Vietnam… Hoang Kim Nhut, a tourist from Ho Chi Minh City shared after his trip in March 2021: “I was overwhelmed while sailing, discovering the beauty of Trang An Scenic Landscape Complex and the National Park. Van Long Nature Reserve. Ninh Binh makes a strong impression on me by its majestic rocky mountain system, diverse ecosystem and unspoiled nature. Hopefully, Ninh Binh will promote the power of this tourism resource in the future.” Connecting important “links” Thanks to the synchronous implementation of solutions in the state management of tourism, promotion and product development, etc., despite being significantly affected by the Covid-19 epidemic, the first quarter of 2021 Ninh Binh still welcomed 619,572 visitors, reaching 50% over the same period in 2020, revenue was estimated at nearly 420 billion VND, reaching 61.3% over the same period in 2020. Humbly acknowledging the achieved results, Dr. Bui Van Manh, Director of Ninh Binh Department of Tourism said: “Besides the above results, Ninh Binh’s tourism products are still duplicated, monotonous, lacking in connectivity end; some products have not effectively exploited resources to create quality products and services with cultural depth. This has greatly influenced the promotion of comparative advantages and enhanced competitiveness of Ninh Binh compared to other destinations in the country. In order for Ninh Binh tourism to truly become a spearhead economic sector, contributing positively to the process of structural transformation and socio-economic development of the locality, Mr. Bui Van Manh said that the “link” is important. The most important thing is to organize promotion and promotion, focus on developing tourism products based on the sustainable exploitation of heritage and traditional cultural values ​​in order to create products bearing the local imprint. and suitable to the needs of the guest markets, especially domestic customers during this time. With the desire to soon recover and develop strongly in the coming time, Mr. Bui Van Manh said that Ninh Binh tourism industry has been implementing synchronous measures such as: Issuing preferential and attractive policies. investment in tourism; Build a safe, friendly and attractive Ninh Binh tourist destination; Promote linkages with localities, diversify tourism products; Develop an overall strategy for promotion, promotion and development of the local destination brand; Applying science and technology, digital transformation in tourism development; Check and promptly handle acts of infringing upon heritage and tourism resources… These are fundamental solutions for Ninh Binh tourism to develop sustainably in the coming time.

Healthy mice were created from freeze-dried sperm stored for 6 years in space. Photo: Teruhiko Wakayama. A new study shows that rat sperm that was freeze-dried and stored on the International Space Station (ISS) for nearly six years didn’t suffer any DNA damage and went on to produce “mice pups” healthy”. The study was published June 11 in the journal Science Advances . According to the scientists, this discovery sheds more light on whether mammals, including humans, can reproduce in space. Combined with ground-based experiments exposing mouse sperm to X-rays, the study found that mammalian sperm cells can be preserved on the International Space Station for up to 200 years. Researchers have long thought that exposure to space radiation can damage the DNA in cells and lead to the possibility of passing mutations on to offspring. The lack of freezers on the ISS has prevented long-term research into living cells. To overcome these limitations, the researchers frozen dried sperm samples from 12 mice and sealed them in small, lightweight tubes and transported to the ISS by rocket without the need for a freezer. Mouse sperm were freeze-dried in glass tubes and stored on the ISS . Photo: Teruhiko Wakayama. Because of the complex mix of different types of radiation in space, scientists say, only simulation experiments to assess DNA damage on Earth cannot capture the reality of conditions. outside our atmosphere. Dr. Sayaka Wakayama, Yamanashi University, Japan, lead author of the study told The Independent : “There are different types of radiation flying around in space, unlike on the ground. For example, there are heavy ions, protons and electromagnetic waves from the rays of the sun.” “It’s very difficult to irradiate and reproduce all these types of radiation at once on the ground, so I think DNA damage in biological samples can only be measured in space,” he explains. . Scientists periodically test small portions of the sample. The samples returned to Earth after 9 months, 2 years 9 months, and 5 years and 10 months, respectively. Mouse embryos developed normally in the laboratory after fertilization with freeze-dried sperm and stored in space. Photo: Teruhiko Wakayama. When the researchers examined the samples using instruments that measured how much radiation they had absorbed and performed tests to assess DNA damage in the cell nuclei, they found a long stay. Long duration on the ISS did not result in DNA damage to freeze-dried sperm. Dr Wakayama said: “The total amount of space radiation absorbed by the ISS, as measured by the Japan Aerospace Exploration Agency (JAXA), is 0.41 milli Gray (mGy) per day. Meanwhile, typical radiation doses used to treat cancers such as solid epithelial tumors range from 60 to 80Gy. “The results of the ground X-ray experiment show that freeze-dried sperm can withstand up to 30 Gy and still be able to produce the next generation,” added Dr Wakayama. The freeze-drying process used in the study is “similar to instant coffee, or freeze-dried fruit,” explains Dr. Wakayama. With food, just adding water can be used “instantly”. The freeze-drying process kills sperm, but when rehydrated and injected into a mouse egg, the sperm can still fertilize the egg, then develop normally. The rehydrated sperm cells, when injected into fresh ovarian cells and transferred to female mice, resulted in the birth of “healthy pups”. Mouse sperm that has been preserved in space for years is injected into egg cells. Photo: Teruhiko Wakayama. Although there is a difference between DNA damage caused by X-rays and space radiation, it can be roughly predicted that freeze-dried sperm can be preserved on the surface of the body, the scientists wrote in the study. ISS for over 200 years”. According to the scientists, a total of 168 mice were born from sperm kept in space for six years, all of which were normal in appearance and had no abnormalities in their gene activity patterns. compared with control mice born from sperm preserved on Earth. Some of these mice were raised to adulthood and were able to produce healthy offspring. Scientists believe that more studies from similar experiments could shed more light on radiation effects and the tolerance of life forms for long periods of time in space. Scientists are also conducting research to find out whether mammalian embryos can develop in zero-gravity conditions. Proposals for this experiment were approved by NASA and JAXA in 2015. In August, frozen mouse embryos will be launched to the ISS, where astronauts will thaw and culture in zero gravity.

Tourists wearing traditional ao dai and masks to prevent the epidemic take pictures in front of Ngo Mon Gate, Hue Imperial City (Photo: Do ​​Truong/VNA) The Department of Tourism of Thua Thien-Hue province said that during the holidays on April 30 and May 1, an estimated 100,000 visitors came to visit and relax in the province. The prevention of COVID-19 has been seriously implemented by the province to tourist attractions, accommodation facilities and visitors to ensure a happy and safe holiday. According to industry statistics Thua Thien-Hue Tourism , before entering the holiday season, estimate the proportion of visitors booking rooms in accommodation facility over 80% in the province. Although after that, the situation of COVID-19 epidemic developed complicatedly in some localities, the number of arrivals during the 4 days of public holidays remained almost stable, only 3-5% of guests canceled their rooms at some hotels . Trends of tourists on arrival Hue Currently, not only focus on staying in Hue city, but many people choose to stay in hotels, coastal resorts, Lang Co Bay (Phu Loc district) where the climate is fresh, the beaches are beautiful and rich in nature. seafood cuisine. Faced with the complicated developments of the situation COVID-19 epidemic In some provinces and cities, on May 3, Thua Thien-Hue Province’s Steering Committee for COVID-19 Prevention and Control decided to suspend bar, karaoke, discotheque, games, and massage service activities. 12 o’clock on May 3. Thua Thien-Hue also requested functional sectors to strengthen inspection of the implementation of the set of criteria for assessing the safety level of COVID-19 epidemic prevention and control for tourism activities; severely punish those who do not strictly comply with regulations on epidemic prevention and control such as not wearing masks, making dishonest medical declarations, etc. to propagate and raise awareness of epidemic prevention and control in the community.

Therefore, in addition to doing well in the prevention and control of the COVID-19 epidemic, the province also focuses on improving the quality and diversifying tourism products. A representative of Laguna Lang Co Resort, in Phu Loc district, said that in order to attract tourists to visit the resort during the summer tourist season, the resort has reduced room rates and attached services such as dining, spa, etc. golf, leisure activities… Because current customers are mainly domestic, many Vietnamese dishes have been added to the menus of restaurants. The resort also introduces many sports activities on the shore and water and team building activities to attract more guests in groups, in the form of MICE tourism (business tourism). According to the Department of Tourism, in addition to the province’s policy, a 50% reduction in entrance fees will be made from March to August 2021 for tour operators that take guests to attractions in the Complex of Ancient Capitals. In Hue, many tourist facilities also offer their own attractive stimulus packages to attract tourists. The units also strictly implement regulations on disease prevention and control to create a sense of peace of mind for visitors.

Singapore Green Plan 2030 is the latest plan with the cooperation and efforts of 05 ministries (Ministry of Education, Ministry of National Development, Ministry of Natural Resources and Sustainability, Ministry of Industry and Trade and Ministry of Transport) to advance to a greener and more sustainable Singapore, while offering more business opportunities and creating more jobs. A City Between Nature, Sustainable Living, Renewable Energy, A Green Economy and a Resilient Future By 2026, Singapore will build 200 hectares of new parks, which are about 8 times the total area of ​​My Dinh Stadium. By 2035, Singapore will have an additional 1,000 hectares of green space. At the same time, Quoc Dao will plant 1 million more trees with the ability to filter an additional 78,000 tons of CO2 for a clean air and plenty of shade. These are some of the key goals of the Singapore Green Plan 2030. Singaporeans and future visitors can expect more nature-based recreational activities, such as hiking, bird watching at the upcoming Nature Parks: Rifle Range, Mandai Mangrove, Khatib Bongsu … Natural parks offer visitors an immersive experience in nature, and also act as green buffers to reduce visitor pressure on nature reserves. Roads in the industrial park will be dense with native trees and plants in multi-layered structures, mimicking those in tropical rainforest. This will make the shady routes wider, cooler and more comfortable for pedestrians. By 2030, the bicycle routes in Singapore will be widened from 460km to 1,329 km. At the same time, the Park Connector Network will be expanded from the current 340km to 500km by 2030 so that tourists and Singaporeans have maximum access to nature. This network will include the Round Island Route, the Rail Corridor and the Coast to Coast trail. Accordingly, all apartments will be within a 10-minute walk from the park. Park Royal Hotel on Pickering in Singapore is designed as a hotel in the middle of a nature garden (Photo courtesy of Trivago) Another prominent target is that 80% of tall buildings will be green. Park Royal on Pickering Hotel’s landscape in Singapore is designed to self-maintain and minimize resource use such as: rainwater collected from the upper floors will irrigate the lower levels of the trees through power without running pumps, while rooftop photovoltaic systems can power the lighting system, in hopes of creating the world’s first energy-free sky garden . In addition, when coming to Singapore, visitors can not help but see the magnificent and magnificent Marina Bay Sands when viewed from afar. This is the first MICE facility in Southeast Asia to achieve ISO 20121 Sustainable Event Management System certification and is one of the largest buildings in Singapore to be awarded Green certification by Construction and Construction Authority (BCA). Mark Platinum, is committed to long-term environmental protection. Schools are also committed to contributing to this green 2030 plan with the goal of reducing carbon use by two-thirds. Mr. Ong Ye Kung, Minister of Transport, said: “We are the only country in the world to stop the increase in the number of transport vehicles. And we are also one of the few countries that has taken advantage of the water cycle and reused the last drop. ” Hopefully in the near future, when tourists return to Singapore, they will be more surprised and interested in a modern, modern country that is green, clean and friendly with the environment.

Mr. Le Tan Thanh Tung – Deputy General Director of Vietnam Tourism Joint Stock Company (Vitours) said that the company’s visitors during the upcoming holidays increased 5-6 times compared to last year, equivalent to the peak time. Pick-up point on the occasion of 30/4 of 2019. For guests booking package tours, there are about 2,000 guests, while there are many retail customers. But according to Mr. Tung, retail customers come close to the new holiday because they fear that the disease might break out. In addition, this year’s trend mainly follows relatives and family groups; Therefore, the company provides a private car tour.

Many hotel and resort owners in Da Nang city said that the room capacity at this time reached 80%, many establishments were full. In addition to family and retail tourists, travel businesses in Da Nang have recorded many MICE delegations from 100 to 500 guests during the upcoming holidays.

Da Nang is ready to welcome visitors back on the occasion of April 30 – May 1.

Currently, most travel companies in Da Nang have restored tourism products that have attracted a great deal of attraction to domestic tourists. In which, focusing on 4 main product groups are the tour “Heritage Journey, Central Paradise”; new tours with high quality from 4-5 days but the price is only around 3 million VND / person; MICE tourism products for corporations and large enterprises; Finally, the group of products to partially stimulate demand, for example accommodation services, shuttle buses, destinations, daily tours, … including products with deep discounts or improving service quality.

Mr. Cao Tri Dung – Chairman of Da Nang City Tourism Association, said that up to this time, tours on the occasion of April 30 to May 1 have been almost confirmed and with very good signals, increased strongly compared with 2020 and nearly recovering compared to 2019, reaching about 80 – 90%. Last year, this time only about 10-20% of businesses reopened, but this year it increased to 70%.

“The annual capacity of welcoming tourists is about 30 million. So, from a business perspective, we affirm that Danang’s resources completely meet the needs of tourists, even with a larger number than today. Even when the international market fully recovers, Da Nang still has the resources and capacity to welcome and best serve tourists “- Mr. Cao Tri Dung said.
