Extended data:

In the folklore of later generations, Motome was reincarnated as a snail girl. The story is about a man named Xie Duan, who is poor and kind and has no wife at the age of marriage. Later, he picked up a snail from the river and raised it in a water tank. During the day, he locked the door and worked under it. In the evening, he came home and found that the house had been cleaned and the food was ready. Out of curiosity, one day he pretended not to go far, but peeped at home under the door.

It turned out that the snail girl came out of the water tank. The snail girl said that she was Baishui Sunv, and God sympathized with Xie Duan, so she was ordered to come down to earth to do her wife's duty. She was expected to stay for ten years. I didn't expect Xie Duan's behavior (voyeurism) to be too dirty and improper, so I had to leave early. But she still left the snail shell as Xie Duan's rice jar. The rice in this rice jar can't be eaten and never lacks.
