? The old house will not fall down after a hundred years of living, and it will fall down after five years of being uninhabited? No matter how many years the old house has been built, as long as people have been living in it, even after a hundred years, the house will not collapse or leak rain. This is because people who live in old houses will be popular, often clean and tidy their houses, and the houses can be repaired in time if there are problems. Moreover, no one lives in the house, even a small problem may lead to the collapse of the house, and the embankment of a thousand miles will collapse in the ant nest, let alone the house, so the unpopular house is easily crushed.
We often see weeds in uninhabited old houses, and some of them have become a paradise for small animals. Snakes, mice, ants and insects dig holes everywhere, which will destroy the structure of the house, the walls will slowly fall off and holes will appear in the roof. Wind and rain will accelerate the collapse of houses, but these problems will not occur in old houses where people live. Many old people are very serious about the maintenance of their houses. When problems are found, they will be repaired in time, so that problems can be avoided as soon as possible.
More and more rural people move to cities to live, so that rural houses are gradually vacant, including some brick houses that have been built for several years. These houses are also very strong when people live, but with the passage of time, in just a few years, these once new houses have gradually become dilapidated and dangerous buildings. So what? The old house will not fall down after a hundred years of living, and it will fall down after five years of being uninhabited? It also makes sense.
