The geomantic theory of Yin House was established at the end of Han Dynasty, and there is a book "Buried Sutra" which can be said to be the originator of Yin House theory. In principle, the bones of ancestors are buried in a living cave, and the gas in the cave enters the bones, which are passed on to future generations, and future generations can get a good luck.
From this perspective, it can really make people go smoothly in all aspects, but this is not a change of luck. First, the bones of ancestors have no influence for more than 20 years at most, and then have little influence, that is, more than 20 years can be full of luck. Many people have the function of haunted house when they are particularly lucky, but once the function is lost, it will obviously degenerate. Second, fortune is the most powerful thing in nature, and the geomantic omen of the yin house only relies on the natural environment's own qi, which is similar to giving hormones to athletes. So in essence, luck is not changing but strengthening, becoming less obvious when it declines and becoming stronger when it is strong. Third, Yin Zhai Feng Shui is not something you can have if you want, nor is it something you can meet but cannot ask for.
Some people naively think that burying their ancestors in a good place will make them prosperous soon, and it will rain continuously. If the influence was obvious in ancient times, in modern times, the role of geomantic omen in Yin houses has been greatly reduced. First of all, the industrial pollution of natural gas is also affected. Secondly, there is nothing feng shui in the cemetery, because no matter how good the cave area is, there are thousands of burials, and the gas will be divided into thousands. At the same time, even if a single acupoint is found, who can guarantee that the environment will not change or be destroyed? As long as a place develops and the environment changes, the effect will be much worse.
Therefore, since ancient times, the case shows that only houses that do good deeds and accumulate virtue are good caves, even if they are buried in the wild. A house without merit, even if it finds a good cave, will soon be destroyed. Therefore, the true geomantic omen of the yin house can not be forced, because the prosperity of a person or a family can not be achieved by external means. Just like those who get rich by illegal means or by cheating others, even the best seclusion in residential feng shui will rapidly decline after a few years because of the loss of virtue.
