<P> Ancient Chinese wooden architecture is among the least studied of any of the world's great architectural traditions from the western point of view . Although Chinese architectural history reaches far back in time, descriptions of Chinese architecture are often confined to the well known Forbidden City 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 manuals, the Song Dynasty Yingzao Fashi and Qing Architecture Standards have never being translated into any western language . </P> <P> Ancient Chinese architecture has numerous similar elements in part, because of the early Chinese method of standardizing and prescribing uniform features of structures . The standards are recorded in bureaucratic manuals and drawings that were passed down through generations and dynasties . 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 drawings as early as the first millennium AD, 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 . </P>
