She entered the 1994 Asian Games as the continent's leading female hurdler. In her first major championship outside Japan she claimed the gold medal with a time of 54.74 seconds – an Asian Games record. It placed her fourth on time amongst athletes that season. However, this mark was not to stand as she was disqualified after giving a urine test that was positive for the banned substance Dihydrotestosterone. She was one of eleven Chinese athletes to fail a drugs test at the Asian Games that year, eight of them being gold medallists. This was the first time a winner of an athletics medal had been disqualified for doping at the Asian Games. Marking a toughening of doping sanctions by the Chinese governing body, she was banned from the sport for four years.
