Qing Structural Regulations
Liang based his research of Qing dynasty architecture on the 1734 Qing dynasty Architecture Method (Qing Gongcheng Zuofa Zeli 清工程做法则例) of the Qianlong era. He also consulted several craftsmen's manuscripts which had been handed down from generation to generation, and he sought guidance with the palace restoration craftsmen in Beijing. The Forbidden City was the subject of an intense object of study, which he documented with modern drawings and a large number of photographs taken by himself and by his wife. In the end, Liang deciphered a large amount of obscure jargon, making it intelligible to students of architecture, and clarifying the structural characteristics of ancient Chinese architecture.
Since its publication, for more than seven decades, it has become the principal textbook on the essence of ancient Chinese architecture. As Liang put it, this book and Yingzao Fashi are the "two grammar books of Chinese architecture".
