Which is more important, birthday or Wu Ge?

Naming eight characters and five elements is more important than three talents and five grids. The former is given priority to, while the latter is for reference only and is dispensable.

Because the three talents and five grids are a set of theories fabricated by the Japanese by studying our ancient metaphysics numerology, and they are easy to master before they know it. As simple as 60 years in China, everyone knows. But people who know numerology know very well that the accuracy of 60 A is extremely low, so it is generally not used. What is different here is that the naming method of "three talents and five grids" was exported to China, became Japanese knowledge, and returned to China.
