Why are the eight characters in a monthly pattern?

Because of laziness. I don't know how to count my fingers, and I'm too lazy to turn over the calendar, so I set the pattern on the main gas of this month. Sometimes I'm right, but I'm right when the main gas is in season, and I'm wrong when the miscellaneous gas is in season. The ancients said that we should study the depth of solar terms, so the seasons and months are not necessarily determined by the main qi, but by the gods of solar terms, so there is the official seal of the god of wealth. Denying the fixed frame of the ancient sages, first, it may be ignorant, and even the books "Three Deaths" and "Yuan Haiziping" have not been turned over. The second is arrogance and boldness. As long as I slap it on the shell, I will freeze it at will. Do you care about my innovation?
