The cause of the spire
1. Due to the climate, there is little rain in many areas of China, especially in the western region. The flat roof is not easy to cause water accumulation on the roof.
2. Practicability: for self built houses in rural areas in China, more consideration is given to practicability and price factors. If the roof is flat, the construction cost will be lower and the maintenance will be convenient. It can also suntan millet, plant flowers, raise chickens and ducks, and put in a solar energy, which is really powerful.
3. Habits: Chinese people have the habit of drying clothes. They have a flat roof at home, which is a large terrace, which can play these roles.
4. At present, the main structural form of building in China is the frame structure with reinforced concrete as the main raw material. The waterproof performance of the floor is relatively good, so there is no need for the spire.
