Haha... The function of family trees is to distinguish between generations... In the past, a family lived together... There were many people. Some people in their forties or fifties may still be with those who are several years old. The children are of the same generation... Having a family tree can better distinguish the seniority... Nowadays, there are very few names named after the An family... So you don't have to worry about whether to name the child according to the seniority... This pair It won't affect the child... If your parents-in-law don't want to... Then you can use two names... Just use the name in the family tree as the title of the book... Once you get the name, just call it by your usual name... Haha... < /p>
