In fact, Bao Zheng in history is not as dark as we have seen. On the contrary, he is a white-faced scholar. It is only in the play that the black face is used to express the integrity and fortitude of the characters, so it is called the black face Bao Gong. The real Bao Zheng didn't have a crescent on his forehead. It was just a scar left when he was a child.
When I was a child, Bao Zheng helped my sister-in-law look for something in the well, but she couldn't find it for a long time, so she had to give up. He asked his sister-in-law to drag him up. In the process of rising, Bao Zheng's head hit a stone. In desperation, his head hit a brick and stone, causing the wound to get deeper and deeper, leaving a scar.
People work in the fields every day, so their skin is black. Only officials in North Korea are pampered at home every day. Black represents laborers and white represents exploiters. Although Bao Zheng is not a laborer, he represents the interests of the people, so these people regard Bao Zheng as their own and give him such an image.
In folklore, some people think that after Bao Zheng's death, he became Yan Luowang and continued to try cases in the underworld. Some people think that he tried cases on earth during the day and became Yan Luowang at night. They think that after death, if a person is framed, Bao Zheng will put him back in the dead to continue his life, and if he is really guilty, he will be sent to hell for punishment.
But these are just legends. It can be seen that Bao Zheng is a very fair person in people's minds.
