What does it mean to sit in the eight-character fortune telling? Please help me explain it in simple Chinese.

In the time of birth, year, month and day are all composed of branches, forming eight characters, abbreviated as eight characters. In birthday parties, "doing" refers to oneself, "supporting" refers to sitting, and also refers to spouse. The eight characters indicate that there are three days in the Japanese branch. The relationship between these three days' work and one day's work (mainly one day's work) is the relationship between me and my life, my life. Being in real wealth means that your wealth has a foundation and your spouse can help you get it. This real wealth is the return obtained through normal business activities.
