What does the new moon on Bao Gong's forehead mean?

Statement 1: When Bao Gong was a child, he accidentally fell into the well and hit the shaft wall. Bleeding, he grabbed a handful of dirt and put it on it. When it's done, it will be crescent-shaped. Statement 2: Bao Gong's second sister-in-law wants to kill Bao Gong in order not to let him compete for property, and let Bao Gong, who is very young, go to the well to help her get jewelry. Just hit the crescent shape made of a stone! Statement 3: It is said that Bao Zheng was ugly when he was a teenager, and his family was poor. When grazing, I was kicked in the face by the bully's mount, leaving a faint scar after the injury. Statement 4: Tumor or birthmark Statement 5: I was trampled by horseshoes when I was a child, and some people said that I was kicked by donkey hooves when I was a child! Because I kind of miss the shape of hooves! Statement 6: Bao Zheng is the place where the stars fall from the sky, which can "break the sun, the moon and the shade at night". So there was a crescent moon! 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. Later, the reason why people recite a crescent moon is that it is a discerning person! Honest and clean! In addition, it is said that people who bend to the left interpret Bao Zheng as a human being, while those who bend to the right interpret Bao Gong as a god!
