Legend has it that after drinking something, you can forget all your troubles, love and hate. When you leave this world and go to another place, you are led by Meng Po in front of Naihe Bridge. Life in the world, how hard it is, this bowl is a relief, and it has completely broken with the past life. Those who have loved, those who can't let go, and those entanglements in the rolling world of mortals will always enter the throat with "Meng Po Tang", solidify in the embarrassing and tearful eyes of Naihe Bridge, and become ethereal and faint. Did you give up? Or the decision to cut sleeves with a knife? It doesn't matter anymore; Because-forget, forget all kinds.

According to the Book of the Prince of Yan, after each temple was punished, the ghost was sent to the next temple in turn, and finally transferred to the tenth temple and delivered to the king of the wheel. The tenth hall is responsible for the incarnation of ghosts. All ghosts sent here to be reborn will be taken to the forgetting stage under the control of Meng Po, so that ghosts can forget their past lives.

According to legend, the practice of Meng Po Tang is to send ghosts to all parts of the Ten Halls, and then add herbs collected from the secular to make a soup similar to wine, which is divided into five flavors: sweet, bitter, pungent, sour and salty. All ghosts who are going to be reborn have to drink Meng Po's ecstasy soup. If a sly ghost refuses to drink, a hook knife will trip his foot at once, and a sharp copper pipe will pierce his throat and force him to swallow it. No ghost can be spared. Legend has it that there is a road called Huang Quan Road, a river called Forgetting River and a bridge called Naihe Bridge. There is an earthen terrace opposite Naihe Bridge, called Wangxiang Terrace. There is an old woman selling Mengpo soup in Wangxiangtai. Forget that there is a stone called Sansheng Stone by the river, which makes you forget everything. Sanshengshi records your past life. We walked across Naihe Bridge, took a last look at the world at Wangxiangtai, and drank a cup of boiled water at Forgotten River. There is no share in this life, so why force it?

"Meng Po Tang" is an ancient legend in China, which was recorded in an ancient book of Zilan family. In that legend, people repeat it from generation to generation. The end of this life is only the beginning of the next life. People who have experienced life again and again can't have memories of past lives, just because everyone drinks Meng Po Tang on Naihe Bridge before being reborn. Therefore, walking on the Naihe Bridge is the last time a person has memories of this life. At this moment, many people still cling to the unfinished wishes of their previous lives, but deeply understand that these wishes can not be realized after all, so they sigh. This is also the reason why this bridge connecting generations is named Naihe Bridge.
