Why do you have to wash dishes after dinner? Why can't there be water in the pool?

Get into the habit of washing dishes after meals. Don't leave them till tomorrow. Try not to leave water after washing dishes. (Also said don't ask why, some things can't ask why) Why is this?

Be sure to wash the bowl after eating. It doesn't look good there. Things like food will end up in that bowl, and it will be difficult to wash it off the next day. Don't leave water in it just because you want to eat it next time. Don't you want to throw water out when you are filling rice or vegetables? That's not too much trouble. They won't tell you that they are afraid of you. I can tell you that there are ghosts in China legend. Ghosts usually appear at night. If you don't wash the dishes after dinner at night, or there are leftovers in the bowl, you will attract ghosts. Just like people who believe in Buddhism, they will pay tribute to the gods. Immortals like to eat tributes, and they must wash dishes after eating at night. It is not good to put bowls in water. Some ghosts drowned.

It is said that a ghost came to eat leftovers. If he doesn't wash the dishes after dinner, he may come to your house for dinner, which is commonly known as the dead man's meal, so he must wash the dishes after dinner, or he will come back for rice.

I also saw this sentence in a personal space today. I also want to know why. I just thought of a terrible answer myself, and that is: if you don't wash the dishes, someone will come and give you the rest of the rice in the bowl. Similarly, so is water.
