Liu made her Olympic debut in Vancouver, skating in all four events: 500m, 1000m, 1500m and 3000m relay. Liu is considered the second-fastest Chinese skater, behind Wang Meng.
In the 2008 ISU world championships, Liu won the silver medal in lady's 500 meter final, and has been a key contributor to China's successful relay efforts. Despite being her least favorite event, Liu's biggest success on the World Cup circuit in the fall of 2009 came in the 1500m, where she was ranked fifth overall and closed out the season with a third-place in Montreal followed by a runner-up finish in Marquette. China's relay team won the last three competitions of the season, and Liu was a member of each of those squads.
