Despite a once promising future, Liang Wenbo was permanently expelled from snooker after being convicted of multiple match-fixing offences.

The 38-year-old was suspended in 2022 alongside nine other Chinese players in what is considered snooker's most significant corruption scandal. Other players who received bans include Yan Bingtao, Chen Zifan, Zhang Jiankang, Bai Langning, Li Hang, Zhao Jianbo, Chang Bingyu, and 2025 World Championship finalist Zhao Xintong.

The World Professional Billiards and Snooker Association (WPBSA) issued suspensions ranging from 20 months to five years and four months to eight players. However, the harshest penalties were given to Liang and Li, who received lifetime bans from snooker.

Liang first made waves in 2008 when he unexpectedly reached the quarter-finals of the World Championships, where he lost 13-7 to Ronnie O'Sullivan. He secured one ranking title during his career at the English Open in 2016, defeating Judd Trump.

However, his career was abruptly ended due to allegations of fixing or involvement in fixing five snooker matches between July and September 2022, charges for which he was later found guilty. He was also discovered to have encouraged fellow players to fix nine matches and violated additional rules by placing bets on matches.
