Abstract:Mr. Liang Sicheng's 'Qing shi ying zao ze li'(Rules of Qing-style Construction)has been reprinted three times since its publication. It is not only the main reference book for college students to learn the history of architecture and survey and map ancient buildings, but also an important reference for ancient building design and construction units. No writing can be perfect, the problems in the format are more concentrated. According to the order of the format of 'Qing shi ying zao ze li', this article is a discussion of three parts: "bucket arch", "wooden frame" and "decoration".
