What is the source of fortune telling? How accurate is it?

It's better not to count, there will be cause and effect. Fortune telling is not good, okay? Everyone is born with their own destiny, because they were reincarnated with karma and blessings in their last life, and fortune tellers have seen all the blessings of your fortune through the methods taught in the Book of Changes. But they are human beings, and they are only the lives of ordinary people! The word lucky in fate is in your own hands, and no one can count it. A good life can turn into a bad life, and a bad life can also turn into a good life, which depends entirely on how people change their luck. If you don't change it, let the person who calculates accurately do it, no matter what it is. You can look at Fan Sixun for details. Later, he taught himself Buddhism and was charitable. Didn't all his bad luck change?
