In old Beijing, the head of a family is generally called the master, and the wife is called the wife or grandmother. The master's son is called the master, the master calls the master's sister the aunt, and the servant the aunt.

The other is to call your daughter aunt or sister-in-law at home. There is a little girl who is spoiled and domineering.

There is a title behind her sister-in-law, which is often the antonym of her.
