Ancient Chinese wooden architecture

 with little else explored by the West. Although common features of Chinese architecture have been unified into a vocabulary illustrating uniquely Chinese forms and methods, until recently data has not been available. Because of the lack of knowledge of the roots of Chinese architecture, description of its elements is often translated into Western terms and architectural theory, losing its unique Chinese meanings.
A cause of this deficiency is that the two most important Chinese government architecture

The Archaeological Record

To some people, all Chinese architecture tends to look the same. This is in part, because of the early Chinese method of standardizing and prescribing uniform features of structures through bureaucratically supported manuals and drawings that were passed down through generations. These account for the similar architectural features persisting over thousands of years, starting with the earliest evidence of Chinese imperial urbanism, now available through excavations starting in the early 1980s. The plans include, for example, two-dimensional architectural drawing

s as early as the first millennium CE, and explain the strong tendency for the shared architectural features in Chinese architecture, that evolved through a complicated but unified evolutionary process over the millennia. Generations of builders and craftsmen recorded their work and the collectors who collated the information into building standards (for example Yingzao Fashi

) and Qing Architecture Standards were widely available, in fact strictly mandated, and passed down. The recording of architectural practice and details facilitated a transmission throughout the subsequent generations of the unique system of construction that became a body of unique architectural characteristics.

, built of Hangtu, was erected beginning in the first millennium BC. Sundried mud bricks and rammed mud walls were typically constructed within wood frames. Hard pounded earth floors were strengthened by heating.

The Timber Frame

A fundamental achievement of Chinese wooden architecture is the load-bearing timber frame, a network of interlocking wooden supports forming the skeleton of the building. This is considered China's major contribution to worldwide architectural technology. However, it is not known how the builders got the huge wooden support columns into position.

Unlike western architecture, in ancient Chinese wooden architecture, the wall only defined an enclosure, and did not form a load-bearing element. Buildings in China have been supported by wooden frames for as long as seven millennia. The emergence of the characteristic articulated
