I'll answer as you say. Chen Jia is a problem of arranging eight characters and determining the year, month and day of the main branch. About, Chen is determined according to the time when you were born. A is a dry day that doesn't take a year. There is a ballad that can be simply recorded. For example, there is a saying that Ding Rensheng is in the Boxer, which means that Ding Rennian's time is defined as the Boxer, and the rest of the time is pushed down in turn, such as Xin Chou, Ren Yin, Gui Mao and Chen Jia. . . . .
Dry creation refers to male life, while Kun creation refers to female life.
Zanggan means that the smell of the earthly branches is not as pure as that of the heavenly stems, and there will be some seasonal air intake and residual air. For example, water is pure, that is, there is a cinnamon water hidden, but ugly soil contains three kinds of heavenly stems: self-soil, cinnamon water and cinnabar.
As for the explanation, there are some stresses, such as marriage, male wealth stars, female ups and downs and so on.
If you want to study it, go online and have a look. My introduction is to see how the eight characters are arranged and how lucky I am, and then I will buy a book like Didi.
