Being a village means having the advantage of geomantic omen, otherwise it would not be a village long ago.
Example 1: If houses are built in rural areas with gas barriers, the probability of deaf-mute disabled families is at least 90%. What are the obstacles and how to observe and evaluate them on the spot? The simplest view is: the so-called gas barrier is an area where dew does not show after 9 or 10 am on a hot day.
Example 2: A mountainous terrain, on the North-South River, is about five miles long. In the past, all the families lived in the east coast, which is the sunny area in the west. Now all the residents live in the west coast, which is the sunny area in the east. Where did the original East Coast families go? According to rumors and surveys, about 30% of the population moved to the West Bank, and 70% of the population lived there for less than one or two generations and died naturally. Only one family lived there for four generations and died of natural causes.
Ex. 3: In another place, the rivers in the mountainous area run from north to south, and now they are repeating the characteristics of the above terrain. The east coast faces the advantage of population decrease and the west coast faces the advantage of population increase. The strangest thing is that among dozens of families on both sides of the strait, only three or four families live on the west coast, one family has two children who have finished college education, and the rest basically go to society in the state of primary school. Why did primitive people choose to live on the east coast? The reason is that the topography of the east coast is wider than that of the west coast, which is convenient for farming and various activities. Why do people now choose to settle in the West Bank? The reason is that the sunshine on the west coast is better than that on the east coast, and the accumulated temperature and temperature difference are relatively obviously higher than that on the east coast. Like this, due to sunlight, there is a temperature difference between the east and west coasts. We can't use a simple "superstition" to sum up the problem, let alone blame the improper use of the compass, and let alone blame the "zodiac". Those places are completing natural selection and natural elimination.
Case 4: The investigation conclusion shows that there are many settlements and surnames in the microclimate environment in mountainous areas, some of which are hearsay and some are not. It is said that the population died naturally after one or two generations of survival. In many areas, the traces of sites left by residents in the past are now uninhabited, which should be considered from the perspective of scientific thinking. This is an obvious example of natural selection and natural elimination in terrain selection. It can also be inferred that the general environmental and climatic conditions have formed such a pattern after tens of thousands and thousands of years of natural elimination.
Decades ago, an old man once said: a small family, moving to a new place, can't lay the foundation for population continuation unless it meets good terrain and good geomantic omen. Looking back now, although this sentence is simple and to the point, it is rich in philosophy of life.
