I don’t think there is any reason. The name has been just a code name from ancient times to the present. In ancient times, people were named according to their generation. Nowadays, people’s names start to count. I don't believe it! In fact, I feel that people are just like animals and plants. With names, there is no mistaking them. This is actually no different from equipment models and so on. If you have already chosen a name for your child, can your child become a high official without studying? Can he get rich without doing anything?
