Xu You is joking.

In the novel Romance of the Three Kingdoms, Xu You was friendly with Cao Cao when he was young, and later became Yuan Shao's counselor. He advised Yuan Shao many times and focused on Xuchang, the capital of Cao Cao. In the battle of Guandu, Xu You went to Cao Cao because his family broke the law, provided important information, and suggested that Cao Cao sneak attack Wu Chao. As a result, he won a great victory. After the battle of Guandu, Xu You followed Cao Cao to Yecheng. He insulted Cao Cao and despised Cao Jun's soldiers, and was killed by Chu Xu in a rage. When Cao Cao saw it, he deeply blamed Chu Xu and ordered a reburial.

However, there are suspects inside. Later, when he left the East Gate, Gu said to the left and right, "This family needs me, so you can't go in this door or out this door." People have white, then see it.
