How good does the fairy family look at hexagrams?

Not so good. At present, all the fortune-telling methods of immortals are based on a series of methods such as physiognomy, eight-character numerology and "qi" developed in the Book of Changes. As we all know, the Book of Changes, as one of the excellent cultures in ancient China, reveals the relationship between nature, the universe and people. It can gradually flourish and spread to this day, and what it says has certain practical effect. The ancients used it to calculate the changes of heaven and earth, and then to calculate the orbits of planets, and even to predict natural disasters, which were often fulfilled. Therefore, we say that the eight-character fortune-telling derived from this also has certain practical basis.
