Why do blind people do not distinguish between ups and downs?

Hello, I have carefully studied the blind school and the traditional Ziping school. These two schools are very different in themselves. The traditional school pays attention to the balance of the five elements, looking for prosperity and looking for decline. The so-called blind school talks about doing things. Whether it is gram, three-in-one game, six reds and wear, etc. They are all called work, and the level and workload of work are different, including the relationship between object and subject and the relationship between subject and predicate, which is very complicated. Blind schools say that good luck depends on good luck and bad luck, and the year depends on the period. This is a bit like traditional schools, but to be honest, I just like the image method of blind schools. Blind schools also add a lot of things, such as tacit understanding, such as not watching meetings, such as self-identity, such as the concept of systems, which I have not finished learning, but to be honest, it is not as accurate as traditional schools. So I stopped studying.
