What is good for you to supplement the five elements must be analyzed according to your favorite god. The choice and use of XiShen should be analyzed according to the rise and fall of the Japanese Lord and the combination of the five elements of the eight characters. It doesn't matter what the five elements lack.
If your favorite god is gold, LMNT, you can make up for it at this time. If you avoid god for gold, the eight characters are short of gold, which can't be made up at this time.
