1, the first argument is: Meng Po was an early celestial official of the HarmonyOS system. She couldn't bear to see that the world after death was still suffering injustice, so she went to Naihe Bridge to set up a cauldron, gave them Meng Po Tang, which could forget the past life, and then entered the next reincarnation.
2. The second statement is that Meng Po was a woman named Meng in the Western Han Dynasty. She didn't think about the past and the future, but only wanted to persuade people to be good. Later, she went to practice in the mountains until the later Han Dynasty. After her death, the Emperor appointed her as a ghost and put her in charge of erasing the ghost's memory. Later generations don't know her name, only know that her surname is Meng, so they call her Meng Po.
3. The third argument is: Meng Po is Meng Jiangnv. She didn't find her husband's bones under the Great Wall. In order to forget her memory, she specially made Meng Po Tang, hoping to forget everything in her previous life. Later, her story touched the Emperor of Heaven, relieved her from the pain of reincarnation, and asked her to cook Meng Po soup for ghosts by Naihe Bridge to forget the memory of past lives.
Documentary record
According to Shan Hai Jing, Meng Po is actually the second daughter of Emperor Yao.
Meng Po is very good-looking, and Emperor Yao likes his daughter very much. Meng Po likes swimming very much, but people who are good at swimming will eventually drown, and Meng Po is no exception. Meng Po finally died in the river while swimming. Later, Meng Po became a god who called the wind and rain, and every time he appeared, he was accompanied by storms. This should be the earliest record about Meng Po.
