Those buildings in China use tenon-mortise structures.

Speaking of the origin of tenon and mortise in China, it may be earlier than Chinese characters. The tenon-mortise structure has been used in China for more than 7000 years. As early as the Neolithic Hemudu culture, tenon-mortise structure was found. After a long period of practice and evolution, it has become more and more reasonable, and the exquisite and complex technology we see now has emerged. What is commendable is that our craft is not complicated for the sake of complexity, but firm, practical and exquisite. There is no need for metal nails between parts, and its precise technology and tight fastening make people feel seamless. Mortise and tenon must be moderately elastic, scientific and reasonable. If the mortise is small and big, it is easy to crack if it is stressed too much, and it is easy to fall off if it is small.

At present, there are many buildings with tenon-mortise structure, such as Wen Yuan Hall, Leshou Hall, Taihe Hall, Baohe Hall and Zhonghe Hall in the Forbidden City. The Hall of Praying for the New Year, the main hall of the Temple of Heaven, the main hall of chengde mountain resort and the temple of Lianjingbo City were built during the reign of Kangxi in the Qing Dynasty.

The Ming Tombs were built in the 11th year of Yongle in the Ming Dynasty (14 13). Lin Gentang in Changling, the ancestor of Judy in Ming Dynasty, covers an area of 1956 square meters. The whole hall is supported by 60 Jin Sinan wooden giant columns with a diameter of1.17m and a height of14.30m..

The first wooden tower in China, located in Yingxian County, Shuozhou City, Shanxi Province, was built in Liao Dynasty about 1000 years ago. 65.84 meters high, equivalent to a 20-story modern building, is the highest existing ancient wooden structure in the world.
