How to learn the Book of Changes? What subjects does Zhouyi contain?

1. If you want to learn the Book of Changes, you must first know what the Book of Changes is. To put it simply, the Book of Changes describes the general things of nature and society, and the laws of development, operation and transformation. The core idea is: Yuan (the initial stage of things, similar to spring, called wood) Heng (the growth stage of things, similar to summer, called fire) Li (the end stage of things, similar to autumn, called gold) Zhen (the hidden stage of things, similar to winter, called water) 2. Master the knowledge of the Book of Changes and know the classification of the Book of Changes. I ching is generally divided into two categories, one is the original I ching; Second, various forecasting techniques derived from the Book of Changes. The first point: The Book of Changes originally described the process of things: occurrence, development, end and extinction. It is reflected in the process of development and change of things. Taking the influence of the operation of the sun on the earth and the role of the earth under the action of the sun as the general guiding ideology, heavenly stems and earthly branches's tools are used to interpret the changes of human and nature. The thought of gradual change and extreme contradiction is consistent with the thought of harmony between man and nature in Huangdi Neijing. The second point: Various prediction techniques originated from the Book of Changes, such as four-column prediction (eight-character prediction), six-stroke prediction (Na Jia Yi method), plum blossom easy number prediction (Xin Yi), Taoist magic number prediction, Wei Zi dou number prediction, Liu Ren prediction, Ming Xue, other faces and palm prints, are different from the above prediction techniques. The following is a brief description of the above-mentioned prediction technology: 1. Eight-character prediction uses the heavenly stems and earthly branches combination of the year, month, day and time of a person's birth, and then matches this group with the "Ten Gods" to represent the five aspects of human social relations and natural environment, and then deduces a person's past and future destiny according to a series of life figures and grams between the Ten Gods. Eight-character prediction is rare because of its complex system and far-reaching function, and modern Yi-ology workers do not understand and misinterpret ancient books, so there is little strict eight-character prediction system. The advantage of eight-character prediction is that it can predict the ups and downs of a person's overall fortune in his life; The disadvantage is that it cannot reflect the subtle details of life, and because of the existence of the same eight characters, it is impossible to determine the social level of people. The rudiment of six-hexagram prediction is eight diagrams, which describes the correspondence and changes of heaven and earth and personnel in nature. With the combination of eight diagrams, the sixty-four hexagrams are matched with the twelve earthly branches respectively, and the twelve earthly branches are transformed into six parents (six parents are symbols representing our social environment and natural environment), and personnel changes are deduced according to the birth and death function between the six parents. The prediction of six hexagrams seems simple, but in fact it is easy to understand and profound. After repeated improvements by masters of past dynasties, the system is very strict. However, because most ancient books are handed down from generation to generation, it is difficult for modern people to understand the nouns and meanings of the ancients, so there are many people who know six hexagrams in a simple way now, and few people can really use them correctly. The advantage of six-year prediction is that it can accurately predict the small things and big things in life and when they will happen. The disadvantage is that it is difficult to predict a person's fate continuously. Third, the prediction of plum blossom easy number was founded by Mr. Shao Kangjie in Song Dynasty, which uses the combination of eight diagrams to produce comparison and function to judge whether things are good or bad. There are special divination methods for plum blossom easy counting, including digital divination, time divination, object divination and external divination. Professor Liu Heng also classified this divination method as plum blossom easy counting divination. Yimei is characterized by his flexible divination and accurate and quick judgment. The disadvantage is that if you predict things for more than twelve years, you can't predict the changes of things every year. 4. Daoism predicts that the legend of Daoism was written by an old man named Sean in Xiapi Bridge in the Han Dynasty, among which Daoism was included. Qimen forecast is divided into yin and yang according to the winter solstice and summer solstice, each in charge of nine Qimen plates, which are divided into eight houses. Each house has a celestial disk (nine planets), a territory (eight houses) and a strange device (heavenly stems). According to the quality of the world, what is measured is determined by a strange combination of instruments. Because there are few versions of ancient books circulating in Taoism, which are traditionally used to select soldiers' time and orientation, they are now adapted into predictions, and there is a lack of sufficient functional relationship in the theoretical system, so the system is not strict and the prediction accuracy is low. There are even scammers who use the "magic door" as a cover. The advantage of Qimen prediction is that one thing is divided into eight aspects to analyze, and faults are more specific, combining time and space. The deficiency is the lack of theory to predict long-term fleeting time. 5. Nomenclature has existed since ancient times, but it has not formed an independent prediction system. In modern times, some people founded Mingxue, which was then spread to Japan and then to the mainland. Nomenclatology is based on the combination of names and strokes, divided into astronomical phenomena, personality and geography, and matched with the number of 8 1 to analyze and predict the good or bad of a person's name, and a person's fate is determined by the good or bad of the name. The naming method is easy to understand and accurate. The advantage is that it is possible to predict the good or bad of a person's life according to his name, but the disadvantage is that it cannot be accurate to every year. 6. Feng Shui Feng Shui is an academic study on identifying and selecting the natural environment. It advocates conforming to nature, and people who conform to the natural living environment will get good luck. If they leave the natural operating environment, they will be unlucky. Feng Shui mainly includes Yang Zhai Feng Shui (home Feng Shui, company Feng Shui) and Yin Zhai Feng Shui (ancestral grave Feng Shui combination). The geomantic omen of Yangzhai is divided into outdoor geomantic omen and indoor geomantic omen, and their geomantic laws are the same.
