Is it bad to do too much fortune telling?

Not good. As the saying goes, don’t ask for divination. Don’t insist on solving problems through divination. Don’t use divination to solve problems that can be solved by common sense. Only use divination to question gods and ghosts when problems that cannot be solved by common sense and difficult problems. If you are sincere, you will be spiritual, and if you don't move, you won't occupy it. But as a Zhouyi enthusiast, it is allowed to improve your level through more practice, but you should not divination important matters for others before you are not at a very high level. Something to do and something not to do. Moreover, those who learn this should not publicize themselves everywhere, and understand that it is not good for others to have too much privacy. People will die in their own abilities.

Many good fortune tellers in ancient times did not end well, so be careful!
