Why does the blind school not care about the strength and weakness of the eight characters?

Hello I carefully studied the blind school and the traditional Zi Ping school, itself is very different, the traditional school is concerned about the balance of the five elements, to find a strong and weak determination of the gods, and the so-called blind school is to do work, whether it is a grams, triad bureau, six and through the six are called to do work, and to do the level and amount of work is different, which also contains the relationship between the object and the subject and the subject of the relationship, it is very complex, the blind school said that the big luck to see the good and bad luck, the flow of the year to see the period, the big canal is the relationship between the ruler and the subjects, this and the traditional school a little bit the same, but to be honest, I just like blind school like method. The blind school says that the Grand Canal and the current year are the relationship between the ruler and the subject, which is a little bit the same as the traditional school, but to be honest, I just like the blind school's method, and the blind school has added a lot of things, such as the secret combination, such as not looking at the square, such as the self-combination, such as the system of the concept of a lot of many, I have not finished the study, but to be honest, it's not as accurate as the traditional school. So I didn't study it.
