generally speaking, Chinese ancient architecture is mainly wood structure, supplemented by brick, tile and stone. From the architectural appearance, each building has three parts: upper, middle and lower. The top is the roof, the bottom is the base, and the middle is the column, doors, windows and walls. Above the columns and under the eaves, there is also a kind of component which is composed of vertical and horizontal wood blocks, which is called bucket arch

this is a unique component of oriental architecture represented by China. It can not only support the eaves and beams and ceiling, but also has a strong decorative effect. The word "Dou Gong" has to be mentioned in the discussion of ancient Chinese architecture. Because of its great changes in the practice of ancient architecture, it has become the most important basis for the identification of ancient architecture

The east gate is named Donghua gate, the west gate is named Xihua gate, and the north gate is named Shenwu gate
the layout of the palace museum can be divided into outer court and inner court. The architectural atmosphere of the inner court was quite different from that of the outer court. The three halls of Taihe, Zhonghe and Baohe were the centers of the outer dynasties, where the feudal emperors exercised their power and held grand ceremonies. With Qianqing palace, Jiaotai palace and Kunning palace as the center, the inner court was the residence of feudal emperors and empresses. In addition, there are Wenhua hall, Wuying hall, royal garden and so on
the hall of Supreme Harmony, commonly known as Jinluan hall, is one of the three main halls in the Forbidden City. It is built on a white marble platform about 5 meters high. There are rows of carved columns standing around the platform foundation, which are called Wangzhu. The head of the column is carved with the pattern of cloud dragon and cloud Phoenix. There are three stone steps in front and back, and the middle stone step is carved with a flat dragon, which sets off the "royal road" of waves and flowing clouds. Inside the hall, there are lefenjinqi wooden columns and exquisite dragon caisson, with a plaque of "justice and brightness" on it. In the middle of the hall is the symbol of feudal imperial power - the throne of dragon carved in Jinqi.

Baohe hall is also one of the three main halls of the Forbidden City, behind Zhonghe hall. The plane is rectangular, with yellow glazed tiles and four corners. Architectural decoration and painting are very fine and gorgeous
the Qianqing palace is at the front of the inner court of the Forbidden City. Before the reign of Emperor Kangxi in Qing Dynasty, it was the place where the emperor lived and dealt with government affairs. After Emperor Yongzheng of Qing Dynasty, he moved to Yangxin hall, but he still read memorials here, selected officials and summoned subordinates
the Jiaotai hall is located between the Qianqing palace and the Kunning palace, which means the heaven and the earth are in harmony, healthy and happy. It was built in the Ming Dynasty and rebuilt in the third year of Jiaqing (1798 AD). It is a square palace with four corners, a gilded top and dragon and phoenix patterns. In the Ming and Qing Dynasties, the hall was the place where the queen held birthday celebrations. Before the empress of Qing Dynasty went to the silkworm altar, she had to check the preparation of the ceremony. Kunning palace is at the back of the inner court of the Forbidden City. It was the Queen's residence in Ming Dynasty. In the Qing Dynasty, it was changed into a place for worshiping gods. Among them, dongnuange was the bridal chamber for the emperor's wedding, where the three emperors Kangxi, Tong and Guangxu all held their weddings
