Zhang Zhen
Liu was coached by Guo Xinming and Zhang Zhen. She took up gymnastics with encouragement from her mother, who had to stop training when her gym closed during the Cultural Revolution. In fact, Liu's decision to continue training for another four years after a disappointing performance at the 1996 Olympics (where she failed to make the beam final because of a fall in the team competition) was partly to realize her mother's unfulfilled dream.
