Emperor Huizong of Song
"Yingzao Fashi" is a technical treatise on architecture and craftsmanship written at the Directorate of Buildings and Construction. The book was completed in 1100 and presented to Emperor Zhezong of Song in the last year of his reign. His successor, Emperor Huizong of Song, had the treatise officially published three years later, in 1103, for the benefit of foremen, architects, and literate craftsmen. The book was intended to provide standard regulations, to not only the engineering agencies of the central government, but also the many workshops and artisan families throughout China who could benefit from using a well-written government manual on building practices.
