What is the layout of quadrangles in China?

Siheyuan has only one yard, surrounded by houses, and is a standard four-bedroom apartment. The gate is usually in the form of a gatehouse, located in the southeast corner. The yard is near a square, with three main rooms in the north and three main rooms in the south. Opposite the main room, there are three east and west wing rooms.

Features: First of all, naturally speaking, quadrangles belong to quadrangles, and the courtyards in quadrangles are closed and open, which can create a good microclimate inside and reduce the influence of bad weather outside. On the one hand, it can effectively shade the sun and enjoy the cool in summer, and it can get good lighting to keep warm and resist sandstorms in winter. The open-air transparent courtyard is both an air inlet and an air outlet, and it is ventilated smoothly by natural wind pressure. In addition, the courtyard is also conducive to drainage and rainwater collection.

At the same time, in terms of social ideology at that time, China and other architectural associations continued for more than 2,000 years, forming a set of strict social behavior norms. The characteristics of quadrangles, such as strict defense, introverted stability and orderly, are highly consistent with this norm, so they have been continuously strengthened in the long river of years, thus forming a unique Chinese quadrangle housing system.
