Seniority is generally achieved by boys. Girls are both desirable and undesirable. Seniority is used to distinguish the elders and younger ones in the family. For example, the oldest person in our village calls me grandpa when he is 17 years old. Besides, ancient families used very strict word selection when formulating seniority, but modern society has distorted it. The meanings of many words just don’t sound good to me. It’s okay if you don’t take them. When you meet someone from the same clan, you will know how to call them by their seniority. Regardless of your age, they will all be sorted by seniority
