What are the embarrassing things about Cao Cao!

The assassination of Dong Zhuo failed, but he barely escaped from Luoyang. Dally with Zhang Xiu's sister-in-law, Zhang Xiu defected, a son died, and Dian Wei escaped. There is a saying in the battle of Puyang: when Cao Cao saw Dian Wei fighting out, he was stopped by the troops and could not get out of the south gate; Turning to the north gate again, in the firelight, I saw Lu Bu galloping. Cao Cao covered his face with his hands and whipped his horse. Lu Bu came from behind and slapped the halberd on his helmet. He asked, "Where is Cao Cao?" Cao Cao pointed in the opposite direction and said, "That's him riding Huang Ma in front." Hearing this, Lu Bu abandoned Cao Cao and went after Ma Xiangqian. Is this embarrassing enough? Cao Cao led the army to meet Ma Chao in Tongguan, and Cao Jun was defeated. West cool soldiers are fierce, and Cao Jun can't resist them. Only Xi Liangbing shouted, "Cao Cao is wearing a red robe!" Cao Cao immediately took off his red robe. He shouted again: "It's Cao Cao with a beard!" "Cao Cao panicked and immediately cut off his beard with a sabre. Someone in the army told Ma Chao about Cao Cao's beard cutting. Ma Chao also shouted, "Cao Cao has a short beard!" "Cao Cao heard the shouts and immediately pulled up his skirts and wrapped his chin to escape. It is sad enough for a person to relive the battle of Puyang, and then it should be Battle of Red Cliffs, not much. . . I don't think so. Thank you.
