When you are away from home, you will always be together, black and white are impermanent. Why did you go out together?
In fact, there are many kinds of souls, such as wandering souls and ordinary ghosts. And if there is black and white impermanence to seduce you, it actually means that you are not bad after death, at least you have not become a vagrant. However, there is actually a place called Elysium in legend. Many people want to go to such a place, but most of them are not qualified.
In fact, there is a folk story about black and white impermanence. Legend has it that black and white impermanence is a pair of good brothers, affectionate and righteous. White impermanence has another name in the world called Xie Bianan, and black impermanence has another name called Fan Countless. About their death, some people say that it was because of a heavy rain, and they had a good relationship. It was raining at that time. Bai impermanent went to get an umbrella and asked Black impermanent to wait under the bridge. Unexpectedly, the river surged, and in order to wait for the white impermanence, the black impermanence did not go, and finally it was drowned. Bai impermanence was very guilty and hanged by the bridge.
Later, Yan thought the two of them were good, so she sent them to the world to catch ghosts. So they are always together.
