Why does the black-and-white impermanence official hat say "When you see money, the world is at peace"? What is their origin?

Black impermanence is called Fan without salvation, while white impermanence is called Xie Bi 'an. As we all know, in China's myths and legends, there is a special place called "hell" after death, and in this hell, there are not only Rebecca and the judge in charge of the trial, but also some evil gods, such as cow's head and horse's face, Meng Po and black and white impermanence. They have their own systems, and they do their own jobs.

There is also a story about this black and white impermanence. It is said that when they were alive, they were brothers since childhood, and they were good brothers who grew up together. Later, they went to the yamen to catch the fast. Once they went abroad on business and didn't want to rain suddenly. Fan Wushou and Xie Bi 'an hurried to find a place to shelter from the rain, but the only place nearby was under the bridge, where they sheltered from the rain.

After a while, Xie Bi 'an saw that the rain was too heavy. Afraid of delaying the trip, he discussed with the government and asked him to wait in the same place and go back to get his umbrella. Fan Wusan agreed, and Xie Bi 'an hurried back. However, shortly after Xie Bi 'an left, the rain suddenly became heavier, and the river surged, reaching Fan's hopeless chest. Fan was afraid that Xie Bi 'an would not find himself when he left, so he clung to the pier. Who would have thought that suddenly a stream of water rushed over, and Fan was drowned or choked to death.

Xie Bi 'an came back with an umbrella, and when he saw that his good brother was dead, he felt guilty and hanged himself in a nearby tree. Arriving in the underworld, Sebian met his good brother Fan Wubao, and they went to the underworld for trial together. The hades were deeply moved by their actions and asked them to stay in the underworld. As for "making money at first sight" on Bai impermanence's head and "peace in the world" on Black impermanence's head, they should express the wishes of the people from ancient times to the present, so they are pinned on myths and legends.
