Birthday consists of heavenly stems and earthly branches. Each word of these branches has five distinct attributes: gold, wood, water, fire and earth. These attributes distinguish yin and yang, and they have the function of resisting or punishing each other. These five elements are different in quantity and strength, and this strong and weak state will have different effects on the Japanese branch. Therefore, different five elements can be divided into two categories. One is the five elements that are helpful to the sun, that is, the five elements that you like to use, that is, the so-called "using god", and the other is the five elements that are harmful to the sun, that is, the so-called "avoiding god", which actually refers to what a person needs or avoids in his birthday. This is what we are talking about.
My teacher, Master Moya, said well that everything should be people-oriented and vary from person to person. No one, everything is empty talk. Everything is one-sided, superficial and unscientific. Only in this way can we have a clear goal, a prominent core and common sense when doing anything. The name is like this, the auspicious choice is like this, and so is the rule of geomantic omen in Yin and Yang houses.
