There are many legends about the "new moon" on Bao Gong's forehead. Some say that they were trampled by horseshoes when they were young, and some say that they painted themselves when they were young (painting a sun with a moon in it). It is said to be a birthmark; It is also said that Bao Zheng is a satellite from the sky, which can "break the sun, the moon and the night".

In a portrait of Bao Zheng in his later years at Baogong Temple in Hefei, Anhui Province, there is no sun or moon on his forehead. The image of "Song Xueshi" confirms the fiction of various legends.

It is impossible for a person to grow a moon on his forehead. The moon in film and television dramas and literary works has two meanings:

1, deify Bao Qingtian;

2. With the bright moon as the pledge, the actual generation refers to the mirror in the heart, praising Bao Zheng's integrity.

In addition, according to storytelling, when Bao Zheng was a child, Bao Gong's sister-in-law wanted to kill Bao Gong in order not to let him compete for property, and asked him to go to the well to help her get jewelry. The crescent moon and the sun are carved on both sides of the well, and Bao Zheng's head just hits the scar on the crescent moon!
