When will the moon above Bao Zheng become the sun?

Gather four moons and you will become the sun. According to the relevant information of Bao Zheng, the moon on Bao Zheng's head can become the sun if all four moons are collected. This is a cold joke, from the internet. Bao Zheng (999- 1062 July 3), born in Hefei, Luzhou (now Feidong, Hefei, Anhui), was a famous official in the Northern Song Dynasty.
