What to supplement is mainly determined by the rise and fall of the five elements of the sun column and the other five elements in the eight characters.
An inappropriate metaphor: a poor man got lost in the desert. We know that the poor man is short of money, but what he needs most when he gets lost in the desert is not to make up money for him, but the most lifesaving things, such as water and compass, which God uses to save lives. Therefore, we must analyze the eight characters in detail and consider the balance of the five elements first!
