Why do fortune tellers say that what happened before is accurate and what happened after is not?

In the future, it is not that things are not allowed, but that fate is changing. The word "fate" means to move. Not fast and vigorous exercise, but slow and quantitative exercise. Sports will change, but some things will get better and some things will get worse. As usual, do good deeds, do more good deeds, and it will be alleviated or even disappeared when it happens. On the contrary, it is not difficult to understand what is not allowed in the future.
