What kind of books do masters who know Yin-Yang and Five Elements read and what kind of books do they read? People who know five lines of gossip are really like some people say. Let someone else write one. Answer the previous question roughly first. Yi-ology is divided into divination, numerology, physiognomy and so on, and divination is mostly used in daily life. Numerology is fortune telling, and physiognomy is reading faces, palms and geomantic omen (also called physiognomy). Each category has many tricks, such as divination, plum blossom easy counting and so on. And divination also belongs to this category, which is different.

The latter question refers to the personality test. From ancient times to the present, there are indeed masters of character testing, such as Dong Fangshuo in the Western Han Dynasty, and Xie Shi who doesn't know the age.
