Your question actually involves many aspects and can be divided into many sub-questions. Let’s talk briefly:
1. Ethnopsychology. Every nation in the world has its own "mysterious complex", especially the Chinese. From the emperors and generals of the past dynasties to the traffickers and pawns, they all firmly believe in the existence of "divine calculations", "mysterious numbers" and "fixed numbers". Generally speaking, these are credible, but do not believe them deeply, as believing them is equivalent to superstition (I will briefly explain this below).
2. Chinese "occult" system. For thousands of years, Chinese mysticism has been profound. Its origins are all in "Sanyi", and its core has three systems. The theory of heaven is in "Taiyi Shenshu", the theory of earth is in "Qimen Dunjia", and the theory of human being is in "Liu Ren". The rest are developed, Ziwei Shu , seven political affairs and four more, Kanyu geography, looking at the stars from the wind angle, fortune telling and divination, the list is endless. However, when you study it to the highest level, you will find that the entire system is a grand "mathematical probability" (must remember it).
3. The true divine arithmetic and the false divine arithmetic throughout the ages. The great figures who assisted emperors, generals and ministers in the past dynasties basically knew the mystical arts, but these people basically did not use it. When Sun Wu wrote "The Art of War", he discovered that many wars in the past had hired diviners to predict the outcome. The accurate predictions were recorded in the military books, and the inaccurate predictions were blocked. So he understood that his military books were not about mystery. , only talking about theory and strategy. In addition, Dongfang Shuo of the Han Dynasty (the real founder of Bazi studies), Shao Kangjie of the Song Dynasty (the founder of the Huangji Jingshi system), etc., are all pioneers of occultism, but they all advocate "amateur fun" (you should be able to figure it out) The truth is, "Those who see fish in the abyss are unlucky!" )
3. The general principle is that "little things can make you crazy, but big things can cause disaster." These mystical sciences are quite accurate in making small predictions among the people. They can calculate small businesses, small fortunes, and major events such as national destiny. For example, the reason why Song Huizong and his son were captured by the Jin soldiers was because of his Taoist country. The master said that according to his prediction, as long as all the guards in the city were removed, he could use the method of exorcism to ward off the enemy. The result... was embarrassing.
4. "Name" and "Reality". Don't be superstitious about those so-called "masters" and so-called "Chinese scholars", they are all deceptive. Chen Jinmian boasted that "the scientific results of twenty years of painstaking research can accurately and magically calculate you in a few seconds without you having to ask: your surname, zodiac sign, place of origin, age, birth season (month and day), occupation, family How many people are there in your family (how many boys and how many girls), how many brothers and sisters do you have, who are you, how many pigs, cows, and sheep do you have? Your car, how many cigarettes are in your cigarette box, how much money is in your pocket... I know what you think and measure everything you have, with 100% accuracy." Do you believe it? He said that he was "awarded the honorary title of 'Chinese Scholar' by the China National Studies Research Association." (Such a title is cheaper than getting a fake diploma, I also have one)
5. Typing is so tiring. In order to open up people's wisdom, I spend a lot of money. A lot of time. Let me put it simply, if you want to go deeper, read more books yourself, and I wish you the best.
