There are so many people talking nonsense. Let me explain to you why children are weak and sickly.
The body Qi of the Bazi is weak, and the Binghuo and Japanese Yen root Qi are mainly supported by the Rizhi Yinmu. However, the external environment of Yinmu is unlucky and suppressed by Jin. If one's natal wealth is abundant, the body will be weak, and the body will not be responsible for wealth. Therefore, one must replenish the body's qi in order to get rich and stay healthy. The most important thing is that in this fate, wood generates fire, causing fire and metal to directly fight with each other. Of course, you will often get sick.
For this kind of innate flaw in fate, it is best to use luck to make up for it. According to your natal fortune, when you go out, it is Yiwei, Jiawu, Guisi, which happens to be the luck of the south. Luck in the south may be good or bad. The auspicious place means that if the body energy is replenished, you can make money at will. Unfortunately, this intensifies the conflict between Fire and Metal, which can lead to two outcomes: either financial fortunes will fluctuate (without affecting ultimate wealth), or the body will fall ill from time to time.
Actually, you should be glad that your child's fortune is fire first and then wood. If you go out, you will have good luck with gold and water. Your child would have died long ago. How could it be your turn to ask this question?
