To be sure, Pan Zhaoyou's eight-character theory was developed on the basis of traditional numerology. He reveals a person's personality and fortune by analyzing the eight words of his birth time. The application of numerology has a long tradition in the history of China, which is recognized and believed by many people.
However, judging the credibility of a numerology theory needs to consider many aspects. First of all, is there any scientific basis to support the validity of this theory? To some extent, numerology is based on observation and statistics, but it lacks scientific verification and demonstration, which makes many people question its credibility. Secondly, many terms and explanations in numerology are vague, and different numerologists may give different explanations to the same constellation, which also leads to theoretical uncertainty and controversy.
To sum up, Pan Zhaoyou's eight-character theory has a certain influence on numerology, but whether it can be completely trusted still needs to be judged according to personal beliefs and practical applications. For numerology, a non-scientific subject, personal beliefs and subjective feelings may have a great influence on the conclusion. If you are interested in Pan Zhaoyou's eight-character theory, you can further understand and apply it by studying and consulting a professional numerologist.
