Why is the number 8 different from that in real life?
For example, the eight characters of Emperor Wu of the Han Dynasty simply do not conform to the actual situation. Judging from his eight characters, he is a beggar, but in fact he is a great emperor in the history of China. And Li Hongzhang, as long as he weighs 2.3, is also a cheap life, but in fact he is expensive. It is for this reason that some people now make crosses in five columns or even twelve characters in six columns.
In fact, fate can be changed. There are clear statements in all four disciplines, so you can search online. There are "three non-counting principles" in fortune-telling: no fortune-telling with good people, no fortune-telling with evil people, and no fortune-telling with practitioners. Because fate is not immutable. The fate of these three kinds of people is uncertain, and they can change the initial state of their own fate.
