Which is the best one?

There are three kinds of divination in Sichuan: Yin divination, Yang divination and Sheng divination (also called Bao divination), among which Sheng divination is the best. For example, in order to give birth to your son early, the fortune teller kept chanting the fortune teller's wishes while throwing his possession on the ground in the hope of being blessed by the "gods". If the two occupants are back to back, it is called yin hexagrams; The two sides of the yang are facing up. According to the folk saying that "yin does not bring disaster, yang does not receive it", both yin and yang are unlucky. And a negative side, a positive side, this balance of yin and yang, is the best "holy divination", Bao Bu.
