What is the principle of Buddhist fortune telling?

Buddhism believes that for fate, birth reflects the result of good and evil in previous lives, while the fate of this life depends on good and evil in this life, and the fate pattern reflected by the eight characters is not allowed. In particular, people who study Buddhism, starting from their hearts, keep precepts and recite Buddha, and even fly to build towers to do good deeds and die in pure land. The fate pattern has nothing to do with the eight characters.
