Is the eight-character marriage accurate?

It makes sense to look at marriage with eight characters, but we can't just emphasize the accuracy, because the eight characters of husband and wife will affect each other, and even the eight characters of children will affect the relationship between husband and wife, so there are many interference factors the day after tomorrow, which will change the marriage life in the eight characters.

For example, a woman's horoscope marriage is very bad, but she just found a man. The eight-character marriage is very good, the two people get along very well, and the woman knows that her marriage is not good, so she cherishes this man very much. Then the woman's life will be changed, and their chances of growing old together are very high.
