This is mainly because the attributes of the surname are very incompatible with the child's horoscope. For example, the child is born in the fire zodiac, but his surname is in the water zodiac, and water is very powerful. When encountering this situation, there are two solutions: first, pay homage to your parents again, and recognize your godmother as your godfather (but it does not have to be a human being, for example, you can recognize a river as your godmother, which is a southern custom); Second, ask a professional to look at it when choosing a name.
