Building French Style is a standard book of architectural design and construction, which was compiled by Li Jie on the basis of Wood Classic by Yu Hao, a craftsman in central Zhejiang, and later promulgated by the Northern Song Dynasty. It is the most complete architectural technical book in ancient China, marking the development of ancient architecture in China to a higher stage. Li Jie, based on his 10 rich experience in architectural engineering, consulted a large number of documents and old rules and regulations, collected the operating rules and technical essentials of various types of work, as well as the shapes and processing methods of various building components told by craftsmen, and finally compiled this "Architectural French" that has been handed down to this day. In the second year of Chongning (AD 65,438+065,438+003), it was published nationwide and became China.
