What is the connection between Yijing and Feng Shui?

So numerology is understandable. It is inevitable that anyone will have doubts. Once other methods can't solve it, it's okay to have a divination and listen to the messy answers. The problem is that in the Book of Changes, the so-called "gentlemen watch its changes and play its business", so we have to play it ourselves. Ancient geomantic omen (called geomantic omen in Han Dynasty and geography in Tang Dynasty), which talked about Yin and Yang, five elements, gossip after tomorrow, river map and Luo Shu, should be related to the Book of Changes. If some people talk nonsense and can't say anything about Yi-ology, the connection is empty and superficial. What do individuals think of some traditional sayings of home feng shui? For example, light in the bedroom should not be above the bed. Don't point at the bed in front of the bathroom. Wedding photos cannot be placed on the right side of the bed, which will be bad for marriage. Does this statement have anything to do with Zhouyi? How does Zhouyi help us to measure the quality of home feng shui? Nowadays, many so-called feng shui sayings are hard to believe. We should believe those statements that are consistent with Yi-ology. If we want to summarize the correlation of some "Feng Shui theory", whether it is personal experience or other people's examples, we must conform to the principle of mathematical statistics, provided that we have a large number of statistical samples, and then use Gaussian distribution method to determine the correlation coefficient, and we must clarify the upper and lower limits. Only when the correlation coefficient is high can a general conclusion be drawn. For example, what people usually say, such as "What about Northeasters" and "What about Shanghainese", are all secular statements without actual statistics, and such gossip cannot be classified as "learning". Similarly, the example you cited is also a one-sided word without mathematical statistics, and it is a one-sided word that cannot find the corresponding truth from the Book of Changes. We don't need to deny some folk or psychological requirements or practices. For example, in Japan and South Korea, the beds of residents there should be placed according to the "waterline", although residents on the roof should also pay attention to the "waterline", even so, it is irregular. In China, all beds are made regularly, and there is no so-called "waterline". The quality of home feng shui is composed of many factors. If you are comfortable, there is no need to "adjust". If there is a problem, we should analyze it in many ways. If there is really a problem with Feng Shui and you need to find a Feng Shui master to adjust it, then I suggest you find a Feng Shui master who can really solve the problem. Will there be experts in geomantic omen? Or learn from some listeners who use Zhouyi to solve Feng Shui problems? What advice do you have for people who want to study Zhouyi to improve Feng Shui? A master once gave a speech to hundreds of geomantic practitioners in public places such as the Great Hall of the People and the Auditorium of the Chinese People's Political Consultative Conference, explaining how to use the compass correctly, how to pay attention to "great geomantic omen", how to use the nine planets for divination instead of looking at the geomantic omen of Yangzhai, how to make the past serve the present, and how to build a modern geomantic theory. There are other aspects of preaching: how to measure three meridians with a compass; How to consider the systematic error and accidental error of traditional compass; How to reason from the perspective of Yi-ology; How to pay attention to people's psychological function; How to emphasize the righteousness of human nature; How to combine with modern scientific knowledge, especially with modern astronomical knowledge. If there are suggestions for people who want to study Zhouyi to improve Feng Shui, I would like to say the following. 1, China's geomantic culture is not mysterious. We should get rid of the dross in ancient geomantic culture and learn to take its essence. 2. The eight-character essentials of learning interest, self-study, optimization and persistence. If you are really interested in Feng Shui culture, start with the study of the Book of Changes and browse some ancient Feng Shui works with some knowledge of astronomy and geography. If someone wants to take "watching Feng Shui" or "adjusting Feng Shui" as a career, I have to suggest that you attend a systematic training class. Since ancient times, there have been different schools of Feng Shui. Such as Luan Tou School and Rational School. Now looking at Yangzhai, the Eight-fast method is popular in the north, and the Confucius-Xuanfa method is mostly used in the south. Kong Xuan Feng Shui originated from the so-called Tianyu Jing written by Yang Junsong. Originally, it was used to look at the ghost house, so "Nine Palace Flying Stars" used the method of small tour year to turn over hexagrams. Now, if we use it to look at villas, we should use the annual inspection method instead. However, no one in society has done so yet. After 20 years of luck, it is now the eighth National Games. I don't understand how the feng shui of an enterprise or a family house will change after the Eighth National Games. At present, the geomantic omen industry in society is still in the state of self-employment, with no contractual responsibility and no guarantee of time and effect. There should be some integration and professional training.
