Bao Zheng's face turned black. There is also a folk legend: at the end of the Northern Song Dynasty, there were frequent wars and people were in dire straits. The Jade Emperor decided to send the barefoot immortal as the emperor to save the people, and sent two stars, Wenqu and Wuqu, to protect him. Barefoot immortal descended to become Song Renzong.
The stars in the sky are in charge of Nandou Xing Jun, and Nandou Xing Jun will give him a Facebook as his earthly appearance. The second song stars come to get it, and the south fights chess, and the stars are impatient. He just took out a handful of Facebook in Xing Jun's bag and went to the lower bound to be reborn. Wen Quxing caught the face of a samurai, so he was a black face since he was a child, and his father disliked his mother. This is the legend of Bao Zheng's bad face.
In the Yuan Dynasty, because of the political darkness, the people expected to be honest and upright, and there were many operas about Bao Zheng's sentencing in Yuan Zaju. In the play, Bao Zheng is portrayed as black as paint, and a crescent moon is outlined in the middle of his forehead with white oil paint, because this eye covers Zheng Can's "breaking the sun at night", which is also a longing and expectation for Qingming politics.
