Mr. Zhu Zuxia's new book, judging from the contents of the book, has absorbed many theoretical essences of the Chen Han School. After some improvement, I personally think it is a masterpiece of systematically sorting out and optimizing the theories of the new school. It is the best numerology textbook in Chinese mainland so far because of its rigorous and thorough structure. I ching has nothing to do with prediction. It's just a book that records the predictions of the ancients. Feng Shui is very serious. You should not learn it without a master. If you make a mistake, many people will be hurt. However, there are still mistakes in his analysis of personal numerology, and the level of gossip needs to be further improved. His three series of suggestions (four-pillar numerology self-study course) will be beneficial.
