As a Singaporean athlete who had trained in China, Yu said she was in a unique position to speak out about the “culture of abuse” in China.
Yu, who has now retired from competitive skating, said there was a “toxicity that plagues aesthetic sports like gymnastics and figure-skating“, adding: “This needs to be talked about.”
“If publicizing my story can raise some awareness, spark some anger, and help others deal with their experiences, then it is more than worth it,” she added.
Her allegations of mistreatment are the latest to rock the world of sports.
Former Australian gymnasts have gone public with accounts of physical, mental and emotional abuse, while activists this week called on Japan to tackle “rampant” mistreatment of young athletes.
The case of a South Korean triathlete who took her own life captured global headlines earlier this month, while bullying and sexual harassment controversies have also emerged in the US and Britain.
