What is Cao Cao's face in The Romance of the Three Kingdoms?

In Beijing opera, white faces generally represent sinister, suspicious, flying and austere characters, such as Cao Cao.

In history, Cao Cao was regarded as a traitor because he held the emperor to command the princes. In the feudal period and even in the old society, as long as usurping the throne was regarded as a big transgression, Cao Cao was portrayed as a white face.

In China's traditional dramas, loyal officials (good people) are usually dressed as red faces, while treacherous officials or bad people are dressed as white faces. Later, people used red faces to represent good people and white faces to represent bad people.

But more often, it means that when doing something, some people say good things, others say bad things, and "red face" and "white face" tease or deceive the parties together. This situation is said to be: "some people sing a good face, some people sing a bad face."

From Peking Opera facial makeup, red face-a symbol of integrity. White face-a symbol of evil. A good policeman and a bad policeman (some say good things, others say bad things) are two people working together, one is a bad person and the other is a good person. The purpose is to win the hearts and minds of the good people, which means that one is positive and the other is negative.
