As the saying goes, "the sky can't afford a house, and the grave can't be empty." Does it make sense for the ancestors to pay attention to it?

In ancient China, most of the population were rural people. They are also very particular about building houses and burying in the countryside. They often refer to geomantic omen to judge whether this place is suitable for building houses or burial. A habit thus formed has become a common saying. There is a saying that "there is no house in the sky and no grave in the air", which is also about building and burying houses. So what does this proverb mean? Does what our ancestors often say make sense?

In fact, most proverbs are easy for everyone to understand, but at first glance, this proverb is a bit difficult to understand, but it is still a bit easy to understand. So what does the sky mean? In fact, the words "heaven can't afford a house, but the earth can't bury a grave" refer to a specific time period, not the blue sky and white clouds in the literal sense, and the underground collapses.

Explain the meaning of "sky" and "air" in detail. In ancient times, our ancestors still respected God. A year's harvest depends on the precipitation in the sky, and only when the weather is good will there be a good harvest. For the gods who avoid disasters and fear the sky, pray for peaceful development and favorable weather in the coming year through astrological divination. There are four "emptiness" in Wei Zi constellation: sky, earth, sky and ten days, so as to avoid being buried when the house is built on the "sky".

"Heaven" and "Empty" are the two most dangerous time periods in the sky, so in ancient times, these two time periods were considered as extremely unlucky periods for building houses and burying. In ancient times, although there were some superstitious elements in the study of this kind of geomantic omen and divination, the attention to building houses and tombs was not as detailed as it is now.
