How many kinds of eight characters are there in total? Can it really decide people's fate?

The eight-character combination is 5 18400. Because there are only about 30 days per month, there are only about half of the eight-character combinations that can appear in the last 60 years, with 260 thousand kinds. At present, there are 654,380+04 billion people in China, with an average of about 5,000 people for each character. 5,000 people can't have the same fate, right? The eight-character character is only a congenital condition, and the result depends on the later fate.

It seems that someone here is doing a cloud, assassination? If you can move, so can I. Let's see whose knife is faster.
