How much is Yijing training?

I ching is an ideology, but the question is, why do you study it? If you want to make a prediction, you can't. You should learn Fuxi's gossip principle and learn to be a man. Now is the scientific logic thought in the era of science and technology, and The Book of Changes should be out of date. What can I do after learning? Be a Taoist or a monk? Because it has no practical value, the master charges several hundred yuan, and the master spends so much time and energy that he can't make a living at all. He asked for tens of thousands of dollars. Students can't predict, so they eat when they go back. Students feel super unworthy. It's really a dilemma.
