曹洪
Apparently, Cao Hong had previously offended Cao Zhen, another relative of Cao Cao who also served as a general in Wei. In 224, when Cao Zhen returned from a campaign, Cao Pi ordered Wu Zhi to host a banquet in his residence in Cao Zhen's honour. During the banquet, Wu Zhi instructed actors to put up a skit to make fun of Cao Zhen and Zhu Shuo (朱鑠), who were fat and thin respectively. Cao Zhen was enraged and he shouted at Wu Zhi, "Are you and your men seeking a fight with me and my men?" Cao Hong and Wang Zhong egged Wu Zhi on by saying, "If you want to make the General (Cao Zhen) admit that he is fat, you have to show that you're thin." Cao Zhen drew his sword, glared at them and said, "I'll kill whoever dares to mock me." When Cao Hong got into trouble later, Cao Zhen told Cao Pi, "If Cao Hong is to be executed, he'll definitely say something nasty about me." Cao Pi replied, "I'll deal with him myself. Why do you need to worry?"
