This is a fortune teller.

Pass and fail in eight-character fortune telling refers to whether a person has a certain ability or trait and the strength of this ability and trait.

The spirit of the same month refers to a person's eight characters, in which the five elements of a certain day coincide with the five elements of a certain month, indicating that this person has good fortune and performance in that month.

On the other hand, the monthly cycle order means that one of a person's eight characters is in a higher position in that month, which shows that this person can play a strong ability and potential in that month.

Good luck means that one of a person's eight characters is lucky, which means that this person can get more opportunities and development in fortune.

It doesn't work. Why? If a person's horoscope can't match the qi, order and luck of the month or it is unimpeded, then the person's performance in the corresponding aspect will be poor or there is no chance.

In short, the words "Tong" and "Tong" in eight-character fortune-telling actually predict a person's ability and fortune performance according to the combination of eight characters, and different characters will have different functions and influences in different positions.
