Why don't the actors who play Zhou Yu draw painted faces?

Zhou Yu is a pupil. The role in Beijing opera needs to draw a painted face in a clean corner, while Zhou Yu, who is both civil and military, belongs to a minority in Beijing opera and does not need to draw a painted face. Painted face is a business in Beijing opera, and the more formal name is clean, clean and clean. When performing on the stage, faces are generally painted with facial makeup, which mainly plays bold, resolute, rough, bold, secretive, aggressive and treacherous men, also known as painted faces.
