Xu Shu was cheated by Cheng Yu and came to Xudu. When Xu saw his mother, he cursed Xu Shu for not knowing Cao Cao's falsehood and said, "Shaming ancestors was born between heaven and earth!" He cursed and hanged himself. Xu's behavior has a distinct tendency to support Liu and oppose Cao, which accords with traditional orthodoxy and is highly praised by the author. At the same time, Xu's action was also a great stimulus to Xu Shu, which strengthened Xu Shu's determination not to make profits for Cao Cao all his life. During the Chibi War, he saw through Pang Tong's real intention of offering a series of stratagems, which scared the daylights out of Pang Tong, but didn't tell Cao Cao, causing Cao Jun's ship to be burned in the war and lost to Chibi. The social effect of Xu's mother scolding Xu Shu began to appear. Mrs. Sun's protection of Liu Bei from Wu is also the author's affirmation of the cultural value and status of women. Because Mrs. Sun spared no effort to accompany Liu Bei to escape from Wu safely, she established a wonderful honor for her prosperity and the tripartite confrontation between the three countries. Many advisers of Battle of Red Cliffs and Cao Cao didn't know it was a trick, only Yuan Zhi saw through Pang Tong's series of tricks. Yuan Zhi is also known as Fu Shan.
