About Yang Liwei
Yang Liwei is a Chinese major general, former military pilot, and former taikonaut of the People's Liberation Army. Although the first Chinese citizen in space, Yang Liwei is not the first person of Chinese origin in space. In October 2003, Yang became the first person sent into space by the Chinese space program. He was chosen from the final pool of 14 candidates to fly on China's first crewed space mission. The vibrations were later discovered to have come from the launcher rocket.
