Xu Sheng
No documentation of this event is found in "Records of the Three Kingdoms", the authoritative historical text for the history of the Three Kingdoms period. It was mentioned in Lu Xun's biography that after Liu Bei retreated to Baidicheng, the Wu generals Xu Sheng, Pan Zhang, Song Qian and others felt that Liu Bei was within reach and they could capture him, so they kept making requests to Sun Quan to allow them to attack Baidicheng. Sun Quan asked Lu Xun for his opinion, and Lu Xun, along with Zhu Ran and Luo Tong, gave their response, "Cao Pi has thousands of troops. He pretends to agree to help us attack (Liu) Bei, but he has other motives. Please make the decision to return (to Wu) soon." Not long later, as Lu Xun expected, Cao Wei forces came to attack Eastern Wu from three directions, which would trigger a series of battles between Wei and Wu between 222 and 225.
