When Meng Po left the Three Realms, he was already in this world. She used to be a scattered official in the sky. Later, she saw that there were countless enmities in the world, and even if he died, she wouldn't let go. She came to the Forgotten River in Hell Building, set up a cauldron on the river bridge, and extracted the idea that the world could not be put into Meng Po's soup for ghosts to drink. Then he forgot his love and hate, unloaded his baggage and entered the next cycle. This view first appeared in Taoist classics in the Spring and Autumn Period. In China's traditional thought, it has the meanings of "people die like clouds", "hundred deaths" and "not remembering the grievances of the undead".
The so-called Meng Po, after crying at the Great Wall, saw countless bodies under the Great Wall and never found her husband's bones. In order to forget these painful memories, we made a kind of Mengpo soup that can make people forget their memories. Later, heaven missed her husband's love, and heaven moved, and the tunnel moved, saving her from the pain of reincarnation, letting her cook Meng Po soup by Naihe Bridge, and letting the souls involved in reincarnation forget everything in their previous lives.
In other words: "The past is over, and the good and evil in this life is only the heart." The theory of meaning was widely spread from Yuan Dynasty to Ming and Qing Dynasties, and it was also the most widely spread. Of all the legends about Meng Po, this one is more realistic.
Born in the Western Han Dynasty, he studied Confucian books since childhood and began to recite Buddhist scriptures when he grew up. However, when Buddhist scriptures were translated into Chinese in the Eastern Han Dynasty, she was still alive. She never recalls the past and never thinks about the future. It was not until she was 8 1 year old that she wholeheartedly advised people not to kill animals and to be vegetarian. She is still a virgin. I only know her surname is Meng, so I call her "Grandma Meng". Later, Grandma Meng went up the mountain to practice until the end of the Han Dynasty. At that time, some people knew the reasons of past lives and often revealed their fate. Therefore, God specially appointed Grandma Meng as the God of the underworld and built a memorial platform for her.
