Why is Liu Bei called Big Ear Thief Sun Quan, blue-eyed thief Cao Cao and Aman in history?

Liu Bei is said to have long ears that can reach the shoulders, the so-called double earlobes and shoulders. His opponents call him Big Ear Thief. It is said that Sun Quan's eyes are not black, a bit like the blue eyes of the Western Regions. Maybe his ancestors had mixed blood and inherited this lineage, so his enemies called him a blue-eyed thief.

Cao Cao's nickname is Aman. Cao Cao's father was adopted by the Cao family, whose real name was Xiahou. After Cao Cao was born, the Cao family was very happy. However, it is said that the Xiahou family who adopted Cao Cao at that time had no son, and they were afraid that Cao Cao would be taken back, so they took the name Aman, meaning to avoid their in-laws.

Of course, this is just a legend. But there was a folk custom at that time, that is, children must have a base name, so as to fool Yamaraja and have a good baby. Mainly because of the underdeveloped medicine at that time, the survival rate of children was low.

Some of Cao Cao's younger brothers or enemies like to call him Cao Aman, which means closeness or contempt.

However, anyone who called him Aman was basically killed by him.
