What are the classic books for learning eight characters?

I have been studying eight-character numerology for 10 years, and I have probably read more than 100 books, but even after reading so many books, I still haven't grasped the essence of eight-character numerology, and I haven't reached the realm of god-like ruin.

The eight-character books published now are mixed, and almost 80% are introductory books. High-level books, less. Even if a high-level book is published, if you don't understand the overall thinking of the author's numerology. Books like this are all classic books that can't be avoided when learning eight characters.

Yuan Haiziping, San Tong Ming Hui, Yu Ziping, Zi Ping's humble opinion, Golden Barrel Cheats

Ziping Needle Boxing, Shenfeng Tongkao, Xingping Huihai, Zhao Yu Ding Zhenjing, and Five Elements Notes.

Lantai's wonderful selection, Zen meditation, three commandments and songs, and poor communication.

As for the eight-character book listed in the answer, please pay attention to the mark in the upper left corner of the picture. I don't want to say you should understand. It basically contains four pillars and eight characters of numerology,,,,

Therefore, the vast majority of numerology scholars who study by themselves, 90% are wandering in the middle of numerology and can't reach the peak of numerology, including myself.

It is necessary to introduce the numerology book "Shenfeng Tongkao", whose full name is Shenfeng Tongkao, written by Zhang Nan (Zhang Shenfeng) in Ming Dynasty. The author studied Yuan Hai Zi Ping for half his life, but he didn't get what he wanted. Once enlightened, he created all kinds of fallacies and heresies, and then invented and founded the five-star theory of truth and falsehood. This method has certain influence on later generations. As for the "authentic" theory, just like other Yi-ology books with this name, it is like going to a place to buy local specialties, getting to know the area, and seeing many merchants and experienced people, they will not choose those richly decorated and hung with eye-catching "authentic" signs, because the real "old brand" does not need key hype, nor titles and signs. Let's not say how authentic this set is, but compared with Yuan Haiziping and San Tong Ming Hui, its usage is different, which is beyond doubt. At the end of 1990s, some people had a little knowledge of Shenfeng Tongkao, but they grafted some theories such as Disease Medicine into the simplified version of The Rise and Fall of Yen, wrote books and started a school, which established the mainstream position in the workshop and influenced it to this day.

Now I recommend some books that I think are useful to improve my horoscope numerology during my reading career for readers' reference.
