Despite this, Jing Haipeng, the captain of this squadron, is a veteran astronaut who comments that Liu Yang is a very capable person and has successfully completed the training. Meanwhile, Jing Haipeng had previously flown into space twice. Liu Wang has been trained in 14-year space programs.

To date, more than 50 women have flown into space. However, space exploration is very important and offers many benefits for identification, but it also has many dangers. To date, astronaut accidents have killed 21 astronauts, including women.
