This means that Ding fire requires Jiamu to grow, but Jiamu is a thick wooden stake or a big tree. If you use wooden stakes to light the fire directly, you will not be able to light it. Therefore, Gengjin (axe) must be used to split Jia (tree) into wood to light Ding (fire). This is a natural process of lighting a fire before cooking in ancient times. But your child has Jihai, and this Jitu must live in the same house as Jia. (Jiaji combines with soil, which can be verified online). It means that when person A appears, he is noticed and snatched away. This is called "combination", and Ding Huo cannot be produced. So this is a flaw in the horoscope. So if you use assertions on the Internet or in books as a reference, sometimes they work and sometimes they don’t, and that’s why. Not comprehensive. All eight characters interact with each other.
