Eight-character fortune telling is a comprehensive analysis of logic and human nature. It is not only a philosophical and logical analysis and operation, but also needs to be combined with the life experience and environment of the predicted person to be more practical and effective. Of course, it is also related to the level of forecasters. Just like the same patient living in a cold home and a hot home, the final effect of seeing a doctor will be different. Just like seeing a doctor in traditional Chinese medicine, the same patient, although eager to hear and ask questions, may see completely different results from high-level and low-level doctors, and some only see the superficial disease and fail to see the deep-seated causes of the disease.
