The mouse wedding, also called marriage of the mouse, mouse's daughter getting married, or mouse getting a bride, is a widely spread folk belief.
As a result, many mouse-worshipping activities have emerged in folklore.
In the Jiangnan area, people often say that mice are harmful spirits and unlucky, so they need to be married off on the night of the thirtieth of the lunar calendar to ensure peace and prosperity for the coming year.
Further south, in some places, it's said that when the mouse's daughter is being married off, every household should fry sesame sugar, claiming it as wedding candy to 'celebrate the mouse's marriage'.
As long as the mouse eats the wedding candy, it cannot come out to harm people anymore.
In some places, people perform 'blessing child witchcraft' following the custom of the mouse's daughter's wedding.
