According to legend, after the death gate, the last road is called Huang Quan Road, and the other side of the road is blooming, but there are no leaves. Flowers and leaves live and disappear, but they miss each other forever. At the end of the road, there is a river called Forgetting River and a bridge called Naihe Bridge. There is an earthen platform opposite Naihe Bridge called Wangxiangtai. There is a pavilion called Meng Po Pavilion near Wangxiangtai. A woman named Meng Po is waiting there, handing a bowl of Meng Po soup to every passer-by. There is a stone called Sansheng Stone by the Wangchuan River. Drinking Meng Po Tang makes people forget everything. Sanshengshi records the afterlife of past lives. Cross Naihe Bridge, take a last look at the world on the homesickness platform, and forget Sichuan with a glass of water. . .

Legend has it that people go to the gate of hell after death, go out of the gate of hell, pass through Huang Quan Road, and come to Forgotten River, which is Naihe Bridge. The bridge is divided into three layers, the upper layer is red, the middle layer is yellow and the bottom layer is black. The lower level is becoming more and more dangerous, and there are ghosts everywhere that cannot be reborn. In life, those who do good, those who have both good and evil, and those who do evil. . .

There is Meng Po on Naihe Bridge. If you want to cross Naihe Bridge, you must drink Meng Po Tang. You can't cross the Naihe Bridge without drinking Meng Po Tang. If you can't cross the bridge, you can't be reborn. Anyone who has drunk Meng Po Tang will forget all the obstacles in this life and present, and enter the road of reincarnation without attachment and start the next reincarnation.

Those who care about this life and those who hate this life will be strangers in the next life. The dead have their own bowls here, and the Meng Po soup in the bowl is actually the tears that the living have shed all their lives.
