I should call my father's brother, sister, uncle ... What's his name?

China has a vast territory and different customs, and different places have different names for the same kind. Here, I will tell you the names of Beijing and Tianjin in the north for your reference.

Dad's brother, your name is uncle, uncle (with great stress, grandpa speaks softly);

Dad's brother, you call uncle;

Dad's sister and sister are both called aunts. In order, they can be called elder sister-in-law, second aunt, old aunt and so on.

Dad's uncle and uncle are both your grandfathers. In order to distinguish them from your own grandfathers, they are also called "Grandpa", "Sir Zhong" and "Master" in turn. For example, your grandfather is three brothers and your grandfather is the second. Then, your grandfather's brother is your father's uncle, so you can call him uncle. Your grandfather's brother is your father's uncle, so you can call him young master or young master. You got it?
