There is a river that stretches for 800 miles, without flowers and leaves. Yellow sand flows everywhere, so it is called huangquan. There is a demon named Meng Po. They are all women. They are resourceful and have different colors. They are good at eating ghosts and cooking soup. Meng Po soup is made with eight tears as the guide. It can be made over a long period of time. The fragrance can pass through the sky. If a ghost drinks it, the previous events will not be remembered—— "The book of the dead volume of the yellow spring"
