《明史·列传·卷一百八十六》
士信怀怨于心。有天士信与宾客游于湖上，闻异响出于芦苇之间，以为是倪瓒。到渔船中去找，果然是他，把他几乎打死，但瓒始终无一言。
士信恚，他日从宾客游湖上，闻异香出葭苇间，疑为瓒也，物色渔舟中，果得之。抶几毙，终无一言。
Shishi disliked Ni Zan. One day, Shishi and his guests were boating on the lake when they heard a strange sound coming from the reeds and thought it was Ni Zan. They entered the fishing boat to look for him and found that it was indeed Ni Zan. They almost beat him to death, but Ni Zan did not say a word.
