What do you mean, eight out of eight?

Some fortune tellers combine the stars in the sky with people's eight-character fate, resulting in a long-standing saying that the stars follow their destiny and the gods enter their destiny. For example, Yi Tian's nobles, Shi Ganlu, wenchang star, Liu Jia's empty death, heinous and so on. There is no overall consideration, only one-sided identification, so the credibility is not high. That's what you mean by eight defeats, but I didn't know that stars also had eight defeats. Because there are too many definitions.
