In 1983 she reached the final of the inaugural World Championships in Athletics, but finished 18th and last with only 1.80 metres.
In 1978 she jumped 1.88 m to improve the record with 10 centimetres. In 1982 she jumped 1.89 m. In 1990 Sato set the current Asian Games record with 1.94 m.
She finished eleventh at the 1984 Summer Olympics, and also won the 1980 Friendship Games. On the regional level she won the Asian Championships in 1979 and 1983 as well as the 1978 and 1982 Asian Games, both times in new championship records (Czech Republic). At the 1986 Asian Games Zheng got the silver medal despite equalling the Czech Republic, as the winner Megumi Sato, too equalling the Czech Republic, achieved the result with fewer failed attempts. Her personal best jump was 1.95 metres, achieved in May 1987 in Fukuoka.
