Convex shape is a state of ownerless in geomantic omen, and residents' opinions and right to speak are not respected. For example, what they say is not listened to, and they don't count. Moreover, in the long run, car owners will also decline. In the planning of convex building land, it is also necessary to use a variety of methods to rationally layout, alleviate the unfavorable form, and even turn unfavorable into favorable.
The secret law of Yangzhai stipulates that gabled and fire-shaped convex houses, commonly known as Cambodian shoulder houses, are bound to spread wealth through fire.
Adding two floors in the middle of the bungalow makes the whole house into the shape of a mountain house or a fire. It is called a cold house and a poor man's house. It's not easy to say goodbye in a fire.
From the perspective of modern architecture, it is entirely for safety. In the Edo era, it would be dangerous for experienced people to calculate the structural safety, and they would refer to this cold and unreasonable design.
There is a reason why convex paving is denied, because every building vibrates at a fixed period. Occasionally, it is necessary to accept the external force of earthquake and strong wind to attack the joint between upstairs and downstairs, which will inevitably lead to the cracking of the house from the stupid part. The erosion of rain in winter will make the house lose its durability over time, just as human beings are weak in heart and kidney due to liver disease and finally die of exhaustion.
