What is the core content of Feng Shui in China? What is the purpose of the folk customs of the houses it contains?

China geomantic omen is the guiding principle and practical operation technology of ancient architectural activities in China. China Feng Shui is the soul of traditional architecture in China. China's geomantic omen, China's architecture and China's gardening constitute the three pillars of China's ancient architectural theory.

In academic circles at home and abroad, a feng shui research fever is rising unconsciously. China is highly appraised by foreign academic circles. In order to define the name of China Feng Shui, it is called China Feng Shui. China Feng Shui is really a university question. China's Feng Shui contains a profound and systematic thinking concept, which is consistent with the code of conduct of China people, that is, easy to reason and easy to construct; It includes the operation techniques and methods of the system, in which "form method" and "reason method" collectively cover the huge and complex system formed in the past 5 thousand years; The ancient geomantic master in China invented the compass, which is a unique geomantic operation tool in China. On the land of modern China, from palaces to houses, from cities to villages, there are still many ancient buildings of geomantic omen, which are living fossils of geomantic omen. There are also old people in the countryside who can tell you about the unique geomantic omen in their hometown. Isn't this worth studying by people engaged in architecture? From a modern point of view, although it contains many aspects that contradict with modern science and technology, it is the result of intermittent research in the past century. So, does China Feng Shui belong to the category of China traditional culture or practical science and technology? So far, researchers seem unable to give it an exact definition from the perspective of modern single discipline.
