Try as it might, China’s sole form of legal gambling simply can’t escape allegations of corruption committed by the officials in charge.

This week, China’s Ministry of Civil Affairs announced that Wang Suying, the former director of the China Welfare Lottery Issuance Management Center, was under investigation by the ministry’s disciplinary inspection and supervisory departments for what was described as “serious violations of the [Communist] Party discipline.”

The 57-year-old Wang began working for the welfare lottery in 2008, eventually rising to director of the Management Center in 2015 before retiring in May 2017.

Wang is the fifth lottery official to have been accused of corruption in the past year and a half, including her predecessor at the Management Center, Bao Xuequan, and Bao’s former deputy Wang Yunge, both of whom were booted from the Party for abusing their positions for personal gain. Two other senior lottery officials were demoted for similar crimes in 2017.
