There is nothing to be sad about. Since it is superstitious, it must not be trusted. The name was given by the parents. It can be said to be a personal "code name", which can be equivalent to 001 002 003... The code name is nothing to calculate. Palmistry, facial reading, birth dates (and zodiac signs) are based on people's own innate "information" and have been studied and studied for generations. It makes some sense.
