Let the ghost reborn in Naiheqiao completely forget all the memories of previous lives, so as to be reborn with peace of mind; The practice is to take human ghosts and medicinal materials collected from the secular; On the other hand, people's tears are collected and tortured into soup. Legend has it that there is a road called Huang Quan Road, a river called Forgetting River, a bridge on the river called Naihe Bridge, and a earthen platform across Naihe Bridge called Wangxiangtai.

There is an old woman selling Meng Po soup by Wangxiangtai, forgetting that there is a stone called Sansheng Stone by the river.

Meng Po Tang makes you forget everything, and Sansheng Stone records your past life. We walked across Naihe Bridge, took a last look at the world on Wangxiangtai, and drank a bowl of Mengpo soup cooked in the forgotten river.
