I saw your comment on Line 5. An online doctor Zheng retorted that only 1 6 is the kind of water, including naming. Is he right?

I really don't know this. I also read some online before giving you a comment, but I personally prefer that 1 and 6 are water, and the rest are for reference. In fact, many things have different calculus and rules, and there is no need to unify them into a model. I'm afraid I can't help you if you want to study it further. I'm just browsing. sorry But you can pay attention to some metaphysical people in Sina Weibo, that is, those with V. What they said still has some theoretical basis. And this is a problem of mathematical logic, which can be used to explain some macro problems. This is also a relatively high philosophical category in ancient China, but if you want to calculate fortune-telling, you must entertain yourself. Even if you want to calculate, you must find someone who really understands. I said some nonsense, hoping to help you.
