In Chinese myths and legends, after death, people have to pass through the Gate of Hell and pass through Huangquan Road. The Wangchuan River is the dividing line between Huangquan Road and the underworld. The water in the Naihe River is blood-yellow, filled with lonely ghosts who cannot be reincarnated, is full of insects and snakes, and is filled with a fishy wind. There is the Naihe Bridge on the Wangchuan River. There is an old woman sitting by the Naihe Bridge. Her name is Meng Po. If you want to cross the Wangchuan River, you must cross the Naihe Bridge. You must drink Mengpo soup to forget the things of your previous life. If you don't drink Mengpo soup, you will not be able to cross the Naihe Bridge, and you will not be reincarnated.
Meng Po Tang has two flavors that need to be searched for in the human world. One is human tears; the other is incense ashes. The human world is a strange place. There are not only people, but also ghosts, spirits, monsters, monsters, and Taoists who have practiced immortality for hundreds of years. Therefore, the experiences of a god, a ghost, and a cat in the human world can be described as erratic. (Part of the story is adapted from real events)
