In fact, traditionally, the genealogy that we call is the concept of "family tree" for foreigners. The core meaning of family tree is "inheritance", which can be expressed by family pedigree, but also implies some intangible inheritance, including the spiritual continuation of a family in ideology and culture.
So, why should family inheritance be reflected through the image of "tree"? Because, family, like a tree, although we are growing in different directions, we have the same root. Has this sentence been explained vividly?
Through a family tree, children can visually and intuitively see the relationship between family members and know where they come from. Nowadays, small families are becoming more and more independent. Children often know only a few people around them and have no idea of the whole family. If you build such a family tree, you will immediately understand that we are not alone. In this way, children's sense of family will naturally be enhanced. No matter where they go when they grow up, they will have a concept of root.
