Many friends who are new to learning horoscopes mostly have some booklets bought at individual small bookstalls. These books are similar to popular science books, and their purpose is to give people who don’t understand horoscopes a little common sense first. sexual understanding. From a learning perspective, these books are useful. But many people don’t know that these books are just equivalent to primary school mathematics textbooks. If you don’t start here, you can’t become a mathematician. If you only know this little knowledge, you will be too far away from becoming a mathematician! So what books are necessary to learn horoscopes? The first recommendation is the 1995 edition of the two-volume "Ziku. Shushu" in the "Collection of Handwritten Books" edited by Ji Xianlin, which contains the complete content of "Three Ming Tonghui". "San Ming Tong Hui" was edited by Wan Minying, a Jinshi of the Ming Dynasty. It is the crystallization of the collective wisdom of countless wise men over a thousand years before the Ming Dynasty. It is the most comprehensive and authoritative classic on numerology so far. Only by thoroughly understanding this monograph can we hope to step into the door of horoscopes. Secondly, I recommend the Qing Dynasty's "Ditian Xu", which is a development and supplement to the "San Ming Tong Hui" and also corrects individual errors in the "San Ming Tong Hui". Finally, it is necessary to collect extensively the books written by many masters of horoscope numerology in the past hundred years, many of which have certain reference value.
