All 13 missing people rescued in Yunnan nature reserve climbers
Rescuers have found all 13 missing hikers in the Yunnan Nature Reserve and escorted them to safety.
According to the headquarters of the operation, at first six missing climbers were found and a local resident who supplied them with supplies. The remaining seven people from the group were found and taken out the next day.
13 hikers go missing on Mount Cangshan after bypassing a checkpoint and starting their ascent without reporting this to the local authorities. More than 200 rescuers, 12 service dogs and eight drones took part in the search for the missing.
China sent more than 53 billion cubic meters of water to the northern regions
China is developing a massive project to bring water from the south to the arid north. More than 53 billion cubic meters have already been pumped along the eastern and middle supply routes. The project has helped refill more than 50 rivers with a total volume of eight and a half billion cubic meters and return more than five billion cubic meters of water to underground reservoirs.
> Eight years ago, this method became the main source of water supply for more than 140 million people in the north of the country, including in Beijing and other megacities. The project includes three routes. The middle route has been operating since December 2014. It carries water from Hubei province and passes through Henan and Hebei provinces, reaching Beijing and Tianjin.
The eastern route was launched in November 2013 to supply water from Jiangsu Province to areas such as Tianjin and Shandong.
The western route has not yet been completed, it is in the planning stage. Earlier, Chinese Minister of Water Resources Li Guoying called for speeding up the continuation of the construction of the middle route and the design of the western route.

Chinese hot air balloon reaches record height for collecting environmental data in Tibet
A Chinese hot air balloon has set a new world record for collecting environmental data in the Tibetan Plateau. The device rose to a height of 9032 meters above sea level and was higher than Everest.
The aircraft was launched from the base camp on the slope of this mountain. The device rose at a speed of 30 meters per second and in 3 hours 14 minutes reached the highest point above the top of the mountain. The weight of the balloon is more than two and a half thousand tons, and its volume exceeds 9 thousand cubic meters.
He Zeqing, Senior Engineer, Aerospace Information Research Institute of the Chinese Academy of Sciences :
“This is the first time we have reached such an extremely high altitude. This is a record for both China and the whole world.”
Instruments installed on the balloon record data on evaporation and composition of the atmosphere. Among other things, the amount of black carbon, dust, carbon dioxide and methane is measured. These data are essential for assessing environmental changes in the Tibetan Plateau.
Wang Yilong, Junior Research Fellow, Tibetan Plateau Research Institute of the Chinese Academy of Sciences:
“We have obtained valuable data for studying how greenhouse gases and climate change affect the ecology of the Tibetan Plateau. In the future, we will use planetary systems modeling and big data analysis to determine sources and removals of greenhouse gases on the plateau. This will give us a scientific basis for moving towards carbon neutrality in China.”
The work with the balloon is led by a research group of 64 people. They represent the Tibetan Plateau Research Institute, Aerospace Information Research Institute and Changchun Institute of Optics, Fine Mechanics and Physics.
Chinese disabled engineer develops improved leg prosthesis b>
Liang Kaiyu worked as an engineer until he lost his left leg two years ago. He decided to modify his prosthesis and became an internet sensation in China.
Liang Kaiyu, developer of the prosthesis:
“It was a tough time. When I took off the covers, I just couldn't see my leg and couldn't deal with it. I was desperate and spent about three months like this.”
Liang felt better when he noticed how many people with disabilities post videos about their lives online. broadcasts. Then he decided to modify his prosthesis and make it more comfortable. Liang added a shock absorber, a charger port, and made a number of other improvements.
Liang Kaiyu, prosthetic developer:
“The modified prosthesis cushions impacts during exercise and jumping. It also received a separate port compatible with external batteries and chargers.
Thanks to the new prosthesis, Liang has no problems with movement. The engineer published his ideas and developments on the Internet and inspired other people with disabilities.
Liang Kaiyu, developer of the prosthesis:
“Many try to hide the fact that they use an artificial leg. But I am different, I want others to know about it. I want to convey to them the idea that we are just like ordinary people.”
Liangadmitted that his experiments were not always went smoothly. He spent an enormous amount of time developing the optimal design. The engineer has shared his data and experience with several Chinese laboratories so that more people can benefit from improved prosthetic legs.
