The eight characters and five elements in the name are more important than the three talents and five elements. The former is the main one, the latter is for reference only and can be used or not.
Because the Three Talents and Five Figures are a set of theories that the Japanese came up with after learning our ancient metaphysics and numerology. They are known for being simple and easy to master. Just like the Sixty Najia in China, it is very simple and clear, so everyone knows it. However, people who understand numerology know that the accuracy of sixty najia is extremely low, so it is generally not used. The difference here is that the naming method of three talents and five patterns was exported to domestic sales, became Japanese knowledge, and returned to the land of China.
