Yes, these three athletics are famous in China. They are all belong to Liaoning team in China, and have same coach Ma Junren. In 1993, their amazing performance in women long distance running shocked the world. I think these information u should known yet.
But in 1994, Ma Junren and his athletics' confliction broke out, Wang Junxia, Qu Yunxia, Liu Dong left the team. During 1995 to 1996, these 3 person back to the team,but the relationship with the coach would not find back.
After this 2 years' event, Qu Yunxia and Liu Dong's form had never been recovered, so they swooned away from people's line of sight. Wang Junxia's form was just ok(although her performance can not compared to the past), she joined the 1996 Olympics,got the gold medal in 5000m long-distance running and silver medal in 10000m long-distance running.
Then Qu Yunxia and Liu Dong retired for the age and form reason, Qu Yunxia retired in 2000 and now teaching in a university in Dalian (a city of Liaoning Province in China), Liu Dong stayed in Liaoning Long-distance running team and became a coach. Wang Junxia also retired later for brain spasm, after retired, she studied Law in a university, and acted some roles in movie and tv, recently she created a running club, but I don't know whether it still work well now.
That's all I know about them, hope these information can be useful to u
