How to become an astronaut? First of all, you cant

[Popular science! You can't snore if you want to be an astronaut] The fourth batch of preparatory astronauts in China has been launched recently. In 1995, China began the selection of the first batch of preparatory astronauts. The basic conditions at that time included the age of 25 to 35 years, height of 1.6 to 1.72 meters, weight of 55 to 70 kilograms, and inability to snore. Now, for the selection of new astronauts, China Astronaut Center has improved the selection criteria and methods based on training experience. (Planning editor Qin Yi, Cui Chenyun)
