Traditional fortune telling theory will be divided into five elements, with the five elements, there are five elements of the relationship, this would have been unquestionable, but the five elements are divided into \”yin and yang\”, it is because the sky stem and earth branch divided into yin and yang, making fortune telling suddenly become cumbersome, there is a positive seal, partial seal, positive wealth, partial wealth, etc., originally very simple things have to be made complicated. The traditional fortune-telling has to talk about the combination, triple combination, and triple meeting, and give the meaning of \”punishment, punch, and harm\”, which further complicates the simple problem. In my opinion, it is not necessary at all. 《The actual eight-character numerology 》, that is called \”the road to simplicity\”, that is called practical.
