《世说新语·自新》
义兴的河中有条蛟龙，山上有只跛足老虎，一起祸害百姓。义兴的百姓称他们是三大祸害，三害当中周处最为厉害。
又义兴水中有蛟，山中有邅迹虎，并皆暴犯百姓，义兴人谓为三横，而处尤剧。
There was a dragon in the river in Yixing and a lame tiger on the mountains. Both were threats to the local people. People in Yixing called them three threats, and Zhou Chu was the most difficult one to deal with.
