How do you explain that their fortune-telling is accurate?

Fortune telling is neither fake nor unscientific. Fortune-telling is an extremely valuable cultural heritage, which comes from the observation of celestial phenomena by China sages. Have you ever thought that fake things, unscientific things and things that are not allowed can be passed down to today? I can tell you for sure that the eight-character numerology is based on scientific theory, so it will be very accurate. It's just not 100% accurate. It can calculate a phenomenon but can't give specific data. For example, it can calculate when a person is developed, but it can't give you specific money. My personal long-term practical experience in helping people tell fortunes tells me that the accuracy of eight characters is above 80%.
