At present, all fortune tellers have learned a series of fortune-telling methods, such as physiognomy, eight-character numerology and "Qi", all of which are based on 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.
The so-called physiognomy, looking at "qi", is just looking at a person's physical state. For example, you are in a bad mood today, and you are depressed and unhappy all day. Anyone with a discerning eye can see that you are unhappy or unhappy. If you are in a bad mood, your face will be bad. The fortune teller will say that your face is bloodless and your forehead is blue. Moreover, when people are in a bad mood, the body will be slow to respond because of the slow thinking of the brain and cannot respond to external stimuli in time, so bad things will happen, such as accidentally falling when walking. This is the basis for the fortune teller to assert that something bad will happen to you in the future. On the contrary, if a person is in a good mood, positive, friendly and willing to help anything today, then the fortune teller says that something good will happen to him.
China's fortune-telling has the same nature as western constellations and tarot cards, and it is a simulation and calculation of the laws of nature and human life. As long as this law is followed, there is a high probability that things will happen. But at the same time, the future is unknown, so this kind of fortune-telling can't fully see a person's fate.
