What are the architectural features of residential buildings in Beijing?

Siheyuan, also known as Siheyuan, is a traditional quadrangle-style building in China. Its pattern is a courtyard surrounded by houses, so it is named quadrangle. Siheyuan has a history of at least 3,000 years, and there are many types in China, among which Beijing Siheyuan is a typical one.

Courtyard is divided into front yard and backyard, which is also called inner room. The front yard consists of a gatehouse and an inverted building. Hanging flower doors are often used to connect the front and back yards, while moon doors are used in some relatively simple houses. The backyard consists of east and west wing rooms, main room and veranda. Some quadrangles, such as Mao Dun's former residence in Beijing, don't have flower gates to separate the front yard, but add a backyard behind the main house to build a back-built house for women to live in.

Brief introduction of courtyard door

The courtyard gate is the main entrance of the quadrangle, which Beijingers used to call "street gate". In today's rapidly changing world, it is difficult for these street gates to judge the level of hospital owners. Wandering in the streets shaded by green trees, many old street doors have become silent history, which brings you endless association and enlightenment silently, just like an old man of a century, telling you his early stories with a trembling voice.
