Chinese taikonauts have "maintained an indomitable spirit while carrying out space exploration," said Zhang Youxia, vice chairman of the Central Military Commission, Wednesday.
Zhang made the remarks at a seminar while listening to reports delivered by Chinese taikonauts Jing Haipeng, Liu Yang and Deng Qingming about their work over the years.
The Taikonaut Corps of the People's Liberation Army celebrated its 20th anniversary last month.
Over the past two decades, 21 taikonauts were selected from the ranks of air force pilots. They have completed six missions, conducted over 100 experiments in space and orbited the earth for a total 68 days and nights.
Zhang called on the military and the armed forces to learn from taikonauts.
About 750 representatives from China's central and state organs, armed forces and youth attended the seminar in Beijing.
