Before and after the house in the rural hometown, there is a drop of water in the planning of the homestead, which is about 5 cm. When building a house, the front tenant needs to leave 5 cm for the back tenant. If 5 cm is not left, there will be no place for running water in the front tenant's house when it rains.
everyone who builds a house knows about dripping water, and it is guaranteed that the rainy water will flow out and will not flow to other people's homes. If someone else's yard is low, you can make a small ditch at 5 cm to let the water flow out, so as not to hurt the harmony.
The so-called dripping eaves, also known as dripping eaves, are polite architectural habits to prevent dripping rain from splashing on the neighbor's open windows. The boundary is divided, and dripping water belongs to its own land. When building a house, it is necessary to retreat and leave dripping land.
