What is a magic number?

Shu Shu refers to various magic systems used in China culture to predict the future and avoid misfortune. Through divination, geomantic omen, numerology, Mengmeng and other methods, the number of objects is predicted, from people, things, homes and ancestral graves to land transportation and national luck. The principle of Shu Shu is basically the Eight Diagrams of the Book of Changes and the Five Elements of Yin and Yang. Art refers to magic (methods). Number refers to rational number and qi number (the law of use), that is, the law of movement of yin and yang and five elements. "Shu Shu is the art of Taoism (the so-called yin-yang family comes from Taoism) and the theory of yin-yang and five elements has always been respected by Taoism (Confucianism, Buddhism and Taoism). Confucianism says that children don't talk nonsense, so they don't advocate it), and use the mathematical theory of yin and yang and five elements to infer the quality of personnel; That is to say, observing noteworthy phenomena in nature in various magical ways to infer the fate and destiny of people and countries has had a wide impact on the politics, military affairs, culture and science and technology of ancient China "(Shanghai Ancient Books Publishing House-publication description of Shu Shu Series). Shu Shu has always been an important part of China traditional culture. In the history of China, it was once a fashion in social life, but its connotation and extension are still unclear, and there is no exact division in academic circles. Witchcraft, which once prevailed in almost all ethnic groups on the earth, is the origin of magical numbers, such as astronomy, calendar, mathematics, astrology, Liu Ren, Taiyi, Qimen, luck, astrology, divination, numerology, physiognomy, geomantic omen, incantation, auspicious choice, miscellaneous trades, health preservation, house art, miscellaneous arts and so on. Generally speaking, the magic number in a narrow sense refers to the magic that predicts good or bad luck; Mathematical skills in a broad sense include astronomy, calendars and so on. Now, the number of patterns usually refers to patterns in a narrow sense. Shu Shu, also known as Shu Shu, is an important part of the five major techniques of ancient Taoism. Shu Shu, based on the restraint theory of Yin-Yang and Five Elements, speculates on the "good or bad" of nature, society and personnel, which belongs to a mainstream branch of Zhouyi research (Zhouyi is a whole knowledge covering the universe and presented to people in a three-dimensional "image" of nature). In fact, it is the "each needs his own needs" of later generations that makes the Book of Changes classified and studied according to the strict division of meaning, image and number. The Book of Changes is all-encompassing, and later generations can choose it at will, so they artificially "split" a perfect whole. It is correct to speak "righteousness"; People who shout "magic numbers" are unique. Never compromise or attack each other. I don't know that the earliest Yijing is the so-called "theory and art come down in one continuous line"-Lianshanchuan and Tibetans. Now, I have to "follow the trend" to "study the number of skills".
