When he was young, due to the underworld, Meng often sat on the bridge of Naihe and watched the people coming and going with a smile. Oh, no, it's just a ghostly thought, why do people cry? Isn't it bad to smile? Then after watching it, she told her friends how funny it was. They can cry, laugh, and shed tears. Their tears are as beautiful as your pearls. When I was still young, Meng still often sat on the bridge of Naihe, but I couldn't laugh anymore because I was too reluctant to let go. She looked at the people on the bridge who were still coming and going as ghosts. She was constantly affected by her own sorrows and joys in her past and present lives. She couldn't let go of her past life and didn't want to go back to the human world. She kept wanting to cry. She thought that if there was something that could make people forget the past, then why not do it. So she turned into an old lady and gave them the medicine by the bridge. Over time, people called her Mengpo and called the medicine Mengpo Soup. But I asked everyone to let go, but I couldn't let go. I could only sit on the Naihe Bridge day and night and sigh.
