On Nov 14, Sun threatened to take legal action over the debt, which further intensified the conflict.
On Nov 23, Wang used Weibo to accuse Sun of sexual assault and corruption. She wrote in detail of how Sun pressured her. The post was forwarded by thousands of users.
She admitted that she took courage from Lei Zhengfu's case.
Lei Zhengfu, Party secretary of Beibei district in Chongqing, was removed from office on Nov 23 after a sex tape between him and his mistress was exposed online.
"But I would never put myself in the spotlight like this unless I was forced to," Wang said.
