In fact, the person who took action wasn't Hu Dingkun, but his good friend and subordinate, Xu Menglai. Learning about Sisi's high-profile banquet for the entire school staff and students and thinking of her usual dressing style and behavior, he came up with the idea that Tian Xinhua might be involved in corruption.
Therefore, he arranged for someone to anonymously write that accusation letter. If Tian Xinhua had indeed embezzled money, that would be great—they could take him down in one fell swoop. If not, at the very least they would disrupt Tian Xinhua's plans. Plus, from what he saw, Tian Xinhua's wife was not the sharpest tool in the shed; maybe the Disciplinary Committee would even manage to catch her slipping up!
Xu Menglai knew all too well that those guys at the Disciplinary Committee were especially good at setting traps. He was very proud of himself for coming up with this idea and sat in his office, eagerly awaiting good news from the Disciplinary Committee.
