Chinese swimming authorities have launched an investigation into cyberbullying targeting three-time Olympic gold medallist Quan Hongchan. The matter has been reported to police. Authorities stated that cyberbullying, malicious attacks, and false information have been appearing online, harming athletes' physical and mental health. The China Swimming Management Centre condemned these acts and pledged to improve athlete protection systems and foster a healthy public opinion environment for sports.

Quan, who won her first Olympic gold at 14, has previously spoken out about toxic online commentary regarding her weight and the immense pressure to diet. Now 19, she considered retirement after the Paris Olympics but decided to continue competing.
