Please tell me, what books should I read to learn this Wei Zi? I hope it's great.

If you really want to learn numerology prediction, I suggest you learn four pillars and eight characters instead of Wei Zi Doodle, because Wei Zi Doodle is an immature prediction technology. After all, there are too many similar charts in the 60th anniversary (up to 88%, and the eight characters have no such problem), and many things can't be solved.

For example, Wei Zi Dudu, who was born in the lunar calendar1June, 9821day (dog), has a lunar calendar, and his horoscope is: it's not the first time to meet a bride. However, in 1982, three similar fate diagrams appear.
