I want to learn. Which is more accurate and quick to get started, fortune telling or geomantic omen?

If you are young, don't learn this, it is divination. Because of your personal experience, culture, age and so on. Divination can't explain it or it's one-sided or it doesn't work. In the final analysis, these are all formed around the Book of Changes. Think for yourself!

Know a little about Taoism, and the learning process is more painful. When I first read a book, I felt like a heavenly book and I was at a loss. I know a little now, but it's still immature! Maybe your talent is extremely high, I hope you achieve something!
