For example, ancient geomantic omen emphasized that houses should be built in the south of mountains and the north of rivers. In other words, the house is best backed by the mountain in the north and the water in the south half ring. In fact, this is based on science. Because according to the climate of our country, there are mountains in the north of the house, which can prevent the northwest wind from blowing directly on the residents, thus creating a relatively mild temperature environment for us without affecting ventilation.
There is running water in the south half of the house. First, ancient houses are all made of wood, which is conducive to fire prevention; Second, running water is not easy to produce all kinds of bacteria, which is beneficial to health; Third, the water in the semi-circular house bends to the north, which means that when the water rises, it will impact the north embankment in large quantities, while the south embankment where the house is located will be relatively safe.
In fact, isn't people's health affecting their luck? If a person is ill and in poor health, naturally nothing will go well.
As for the current theory of ghosts and gods, I personally think that in order to convince the younger generation, these empirical knowledge will gradually add some scary things to make the younger generation afraid to listen. But after a long time, it has gone bad. It has gradually become the mysterious "Feng Shui" today. Therefore, we can dialectically look at Feng Shui, and righteousness and goodness will be passed down.
Shallow knowledge, don't be surprised by mistakes.
