The pair have been found to have fixed snooker matches, persuaded or encouraged other players to fix matches and bet on matches, among other rule breaches. They have until June 20 to appeal against the decisions.
Eight other Chinese players have been suspended, including former UK Championship winner Zhao Xintong who was banned for one year and eight months, and Yan Bingtao, the 2021 Masters champion, who was banned for five years.
