Yi Mingxuan’s knowledge of naming is, to be precise, the methods and knowledge of grasping, adjusting, and changing the trend of personal luck. Yi Mingxuan was named. The three elements of destiny: those are Bazi, Feng Shui, and name. The birth date is the internal cause of destiny, that is, the main body of destiny; Feng Shui is the living environment of a person and the influence of external conditions on destiny; the name is the external manifestation of destiny. If fate is compared to the body, then the name is the clothes. It not only reflects the owner's hobbies and tastes, but also protects or destroys the owner. It can be seen from this that we can not only understand destiny through names, but also influence destiny through names, which can play a remedial role in the defects of destiny.
