The custom of China for thousands of years is burial, which is called burial when people die. All rural families have ancestral graves. People who die in ancestral graves belong to ancestral graves, but those who die suddenly but don't go into ancestral graves are ghosts. In the past, my ancestral grave was my incense place, and the incense place was my ancestral property. People in places without incense are buried in mass graves after death, but they are also buried in loess. In some central areas, some rich people are superstitious about Yin House Feng Shui. Because they believe that good geomantic omen can make future generations prosper, they choose cultivated land as a treasure from the perspective of geomantic omen. Some people have little money, but it never rains but it pours at home. They found Mr. Feng Shui and finally chose the cemetery on their cultivated land. So although these people have many barren hills and wasteland to choose from, from a superstitious point of view, the old man is still buried in the crops after his death.
There are fewer people now, so burying the dead with soil is robbing the living, so the dead in the city go to the cemetery, and the people in the countryside still go to the ancestral graves. Now the ancestral graves in the countryside are all in the crop fields, because there is no wasteland in the countryside. There is little arable land in mountainous areas, and crops are planted on terraces. After death, the central area that can be buried is very rich; In the middle of Bosha Mountain, the proportion of farming air is of course greater, and there are also many wasteland to bury people. In our central area, there is no wasteland, only cultivated land. After death, there is no choice but to farm. Generations of people have died in farmland.
Dead people in rural areas are not allowed to be buried in crops, so give them a cemetery. They can't afford to die unless you give it to them and make them pay for it. But you can't live forever. You will die. You can't afford a cemetery, and you can't afford to be buried in the sky without majesty, so you have to go to the ancestral graves in the farmland. Because the ancestral graves are yours, not yours.
