How to determine Ryutsuki, the palace of life?

I am also studying your question, because the cycle of the palace is repeated once a month. For example, if I get sick on 1, I will get sick on the 25th of 13, which is definitely wrong. I think this question has involved some core things. It is not as simple as making a big and obvious difference between four changes, and 80% professionals will not answer it.

One more thing: If those core things will affect the arrangement of the upper level, then the traditional Ryutsuki time limit and the minimum limit circulated on the Internet may also be inaccurate, so it will be boring to tell you. Baidu yourself,

Finally, the daily flow disk is aligned, and the running time is similar. This is a watershed in amateur and professional fields.

All the above are my thoughts from an amateur perspective, hoping to attract more attention.
