The second batch of astronauts, five men and two women, announced

China's second batch of astronauts was selected in May 2009. After three stages of review, five male astronauts and two female astronauts were selected from the active pilots of the Air Force. These astronauts all had a bachelor's degree and were between 30 and 35 years old, with an average age of 32.4 years old. Among them, five male astronauts were active Air Force fighter pilots and two female astronauts were active transport pilots. Most of them had carried out major flight missions such as earthquake relief and military exercises in the Sichuan earthquake. They had excellent flight skills and excellent psychological quality. These astronauts would receive intense and arduous learning and training tasks in order to realize the transformation from pilots to astronauts as soon as possible and shoulder the mission of China's manned space flight. Compared with the first batch of astronauts, the selection criteria for the second batch of astronauts paid more attention to the age factor. When they were selected, they were generally around 30 years old, nearly 10 years younger than the first batch of astronauts. In addition, the selection of the third batch of astronauts would be more relaxed. Not only would they have to select aerospace pilots from the Air Force pilots, but they would also have to select engineers and technicians from the professional fields of aerospace related technology to meet the needs of aerospace flight engineering.

The second batch of astronauts appeared in 2016 and 2022. In 2016, Chinese astronaut Ye Guangfu made his first public appearance. He was one of the second batch of male astronauts. In 2022, the Shenzhou 14 astronauts made an official appearance at the Jiuquan Satellite Launch Center, including Chen Dong, Liu Yang, and Cai Xuzhe. Therefore, the second batch of astronauts appeared at these two points in time.

The second batch of astronauts consisted of Liu Yang, Wang Yaping, Chen Dong, Tang Hongbo, Ye Guangfu, Cai Xuzhe, and Zhang Lu.

The second batch of astronauts had been in the sky for the longest time. He waited for about 12 years and 7 months, from May 7, 2010, when he was selected as the second batch of astronauts to November 29, 2022, when he carried out the "God 15" mission.

The second batch of astronauts consisted of seven people, but no specific information was provided about their retirement. Therefore, it was impossible to determine whether any of the second batch of astronauts would retire.

The third batch of astronauts included Chen Dong, Liu Yang, Cai Xuzhe, Zhu Yangzhu, and Gui Haichao.

The crew of Shenzhou 18 had been announced. The crew consisted of three astronauts, Ye Guangfu, Li Cong, and Li Guangsu, with Ye Guangfu as the commander. The three astronauts were all born in the 1980s. They would carry out the Shenzhou 18 manned flight mission. Ye Guangfu had carried out the Shenzhou-13 mission before, while Li Cong and Li Guangsu were on their first mission. The Shenzhou 18 mission would last for six months, and Ye Guangfu would become China's first astronaut with a total flight duration of one year. This mission was China's second manned launch mission this year and the world's fourth manned launch mission this year.

China's third batch of 18 astronauts had been selected, and they would continue to carry out space station missions. This group of astronauts included seven space pilots, seven space flight engineers, and four load specialists. After more than two years of training, they had already completed all the basic subjects and most of the professional technical subjects. According to the space station application and development phase follow-up mission planning, some of the third batch of astronauts had begun targeted training for follow-up missions. In the near future, some of the third batch of astronauts would join the flight crew of the space station mission and gradually become the main force.

There were different versions of the Black and White Ghosts 'genders. Some folktales believed that the Black Impermanence was male and the White Impermanence was female, but in fact, the Black Impermanence and the White Impermanence were two males. They were sworn brothers when they were alive. In folk legends, they were described as messengers of the netherworld, responsible for guiding people's souls. However, there was not enough evidence to determine their true gender. Therefore, it was impossible to determine whether the Black and White Ghosts were two men or one man and one woman.
