This paper is the second part of the comparison between twobooks about the Ch'ing building constructions-the Kung-chengTso-fa Tse-li proclaimed by Ch'ing Royal Court and the Ch'ing-shih Yin-Tsao Suan-li Chi Tse-li edited and written by Liand Ssu-Ch'eng. Basically the Kung-cheng Tso-fa Tse-li was aimed at controlling all the major materials and labors of the official buildings. Therefore all the 27 buildings in the former 27 charpters areedited according to the scale and the type of those buildings. All the components of the wooden frames listed under each building and the wooden bracket system within the following 13 charpters are arranged according to the constructing and assembling procedures of the framework. Furthermore, the width, depth, and height (that is, the dimensions) of each component are very closely related to its function and location, and with relative components in the framework. But, in Liang's book, what we find out are the general rules about the composition of Ch'ing buildings rather than the system of caculating the dimensions of building components. We also discover that all the relations on dimension, such as the width and depth of a building, the diameters of columns and the depths of beams, or the depths of relative beams, have been changed to certain proportional relations. Therefore, the well-knited relations on dimension between components and the whole building have been obscured.
