The Great Wall built in the Sui Dynasty, the Temple of Heaven in Beijing and the Anji Bridge in Zhao County, Hebei Province have long been at the forefront of bridge science in the world in terms of the perfect combination of technology and art; The existing wooden tower of Fogong Temple in Yingxian County, Shanxi Province is as high as 67. 1 m, which is the highest existing wooden structure in the world. The Forbidden City in Beijing in Ming and Qing Dynasties is the largest, beautifully built and well-preserved large-scale building complex in the world. As for the classical gardens in China, its unique artistic style makes it a pearl in China's heritage.

Ancient architecture in China is characterized by eaves (roofs), supplemented by traditional humanistic spirit and legends, and every inch of the building is full of meaning and geomantic pattern. For example, the quadrangle group layout of the Forbidden City and Beijing Siheyuan symbolizes the inner meaning of "round place" and wealth. See Baidu Encyclopedia "Ancient Buildings in China" for details.

Beijing Forbidden City and Beijing Siheyuan

(Layout of Courtyard Group)

There is a simple organizing rule in the plane layout of ancient buildings in China, that is, every house, palace, official residence, temple and other buildings are surrounded by several single buildings, some cloisters, fences and other courtyards. Generally speaking, most courtyards are connected in series, reaching the backyard through the front yard, which is the product of China's feudal society's thought of "orderly aging, different inside and outside". The main characters in the family, or people who should be isolated from the outside world (such as girls from aristocratic families), often live in courtyards far from the outside door, forming a deep spatial organization of courtyards after courtyards. How deep is the courtyard written by Ouyang Xiu in Song Dynasty? In other words, the ancients once described the residence of a big bureaucrat as "the door is as deep as the sea", which vividly illustrated the important features of the layout of China architecture. At the same time, this courtyard-style group and layout are generally designed symmetrically along the longitudinal axis (also known as the front and rear axis) and the horizontal axis. The more important buildings are placed on the vertical axis, and the secondary houses are placed on its left and right sides on the horizontal axis. The group layout of the Forbidden City in Beijing and the northern quadrangles is the typical example that best embodies this principle of group layout.
