The eight-character life depends on the decline of the sun, when to use the monthly branch and when to use the annual branch.

It's better to learn Buddhism than to play eight characters! I used to like to study the eight-character numerology, but later I entered Buddhism to solve the confusion of life. I advise you to enter Buddhism.

Your problem is, as long as the earthly branch of the monthly order is not broken, use the monthly order to decide the rise and fall. If the monthly order is empty, it can't be used. If the annual branch and the daily branch are at the same time, the monthly order cannot be used, and the annual branch is used instead.

There is a reposted article in the last study space, which is the feeling of a master of Yi-ology changing to Buddhism. You can refer to it if you are interested.
