Why did Chaoshan Anzao invite his aunt?

It is a custom to invite aunts in Chaoshan Anzao. The sixth day of the sixth lunar month is a special day in the Han tradition, because families with married daughters on this day should invite their married daughters home and treat them well. As the saying goes, on June 6th, please ask menstruation to stay in Chaoshan, because menstruation is an elder, and it is a common custom of Chaoshan people to offer sacrifices to the kitchen god at the end of the year. There are two main activities: one is to offer sacrifices to the kitchen god and send him to heaven. The second is all-round cleaning, commonly known as color plate hoarding. Kitchen God, the legendary kitchen god, is called Shen in Chaozhou dialect.
