The quadrangle in Beijing is famous because it is a residential building, but it contains profound cultural connotation and is the carrier of China traditional culture.
The construction of quadrangles pays great attention to geomantic omen. From site selection to determining the specific scale of each building, it must be carried out according to the theory of geomantic omen.
Geomantic omen theory is actually an ancient architectural environmentology in China and an important part of China's traditional architectural theory. This geomantic theory has been guiding the architectural activities in ancient China for thousands of years. In addition to the theory of geomantic omen, the decoration, sculpture and painting of quadrangles also reflect folk customs and traditional culture everywhere, showing people's pursuit of happiness, beauty, prosperity and auspiciousness under specific historical conditions. For example, the pattern composed of bats and longevity characters means "longevity", and the pattern with Chinese rose flowers in the vase means "peace in the four seasons". Auspicious words embedded in the door tube and the door head, couplets pasted on eaves columns, and masterpieces of calligraphy and painting hung indoors are all ancient sayings that combine the achievements of sages and philosophers, using ancient and modern famous sentences, or praising the beauty of mountains and rivers, or inscriptions.
In old Beijing, besides the Forbidden City, royal gardens, temples, temples and palaces, a large number of buildings are the homes of countless people.
An Examination of Old News in the Sun quoted a poem from the Yuan Dynasty: "Clouds open and close three thousands of feet, and there are ten thousand pagodas in the fog." This "one million family" house is now called Beijing Siheyuan.
Why is it called "Siheyuan"? Because this kind of house has four rooms: the main room (north room), the inverted seat (south seat), the east wing and the west wing, which are surrounded on all sides to form a zigzag shape with a central courtyard inside, this quadrangle-style house is called quadrangle.
