Someone asked in the classroom yesterday: The division of physical strength and weakness is actually one of the important topics in the Four Pillars, but it is actually a very complicated topic. Generally speaking, those who help the body for a long time are strong (that is, there are more seals than the robbers), and those who restrain the body are weak (that is, those who hurt wealth and officials kill more), and the simplest way to divide it is Subject to the following three conditions:
1) Delegate: The order of the month is the order of the robbery, and there are also those who call the order of the moon as the seal, but in fact, the power is not as great as the order of the robbery;
2) Obtaining the land: There are many people born from the earthly branches other than the month of obtaining (i.e. Yinbi Jie, etc.), but it should also be noted that the power of the Yin root is not as good as that of Bi Jie;
3) Gaining power: Those who have received more help from other seals than kalpas will gain power for them.
However, such a division method is relatively crude, and is only suitable for beginners to understand a general concept, but in fact, the following conditions must be paid attention to:
4) Which is revealed? Which can only be hidden? Which is only exposed without root? If the root is strong, it will be exerted. The power of those who are not penetrated will only be released from time to time and cannot fully play a role (according to personal experience, the general power is only exerted between the earthly branches). About 50%, depending on the combination (there is also a saying that it does not work at all, but in my personal experience, this is less reliable). As for those who are only exposed but have no roots, they are like catkins in the wind, and their strength is probably only between two and five.
5) Which is the synthesis? Does the monthly order change with the combination? Those who merge and transform will hide two or more powers. If they are mixed and impure, the power will be divided, and the original power of the five elements is still hidden in it. From my personal experience in operation, this statement is also less reliable); and the follow-up of the moon order will affect the overall situation, but the follow-up of the moon order will only happen when the overall strength is one-sided (that is, as the Taiwanese say: watermelon depends on Big side!)
6) Merge but not merge? The power that does not transform will be bound, and the performance will be 20% to 40% of normal (depending on the pattern, there is also a saying that the strength will be lost when combined without transforming, but from my personal experience in operation, this It's also less reliable), but it's a matter of time, and when it's completely dry or exhausted, the strength will be greatly restored.
7) How much is compounded? If there are many combinations, the power will be mixed and impure. When the five elements are purely calculated, the power will be poor, and it will also change greatly with the age.
8) How much is the punishment to be punished? When being beaten, both sides will lose their strength. The more injured person will lose more strength, and the less injured person will have less strength reduction, and the number of injuries will be more. Three times can be regarded as powerless.
9) Have you cleared customs? In numerology, there is a saying of "greed for life and forget about restraint". When it is originally a relationship of rushing, it is happy to see customs clearance appearing from it. Those who are born gain strength, those who give birth to others lose their strength due to discouragement.
10) Who is the commander of the month? Is it clear or not? Whoever gets the order and whether it is revealed or not will also affect the overall strength and balance.
11) How about Nayin? The four pillars of Nayin will also affect who is powerful.
In fact, there are too many factors that affect who is stronger and who is weaker, so I can only briefly talk about it here. In my numerology teaching career, I focus more on the discussion of examples, and less on the general theory. It is also easier to understand the rationale. However, learning numerology is still like learning to climb a mountain. Only by practicing it yourself can you experience and comprehend it. I hope the above humble opinion will help you understand.

Numerology, like other learning, can only make great progress by studying and practicing more. Some people spend their whole lives studying it, but they still lament that the learning in Yiyi is boundless! There is really no one step that can reach the sky! Learning, if you don't advance, you will retreat. I hope you can share it!
