 Much of the knowledge about early Chinese architecture was passed on from one tradesman to his son or associative apprentice.However, there were several early treatises on architecture in China, with encyclopedic information on architecture dating back to the Han Dynasty.The height of the classical Chinese architectural tradition in writing and illustration can be found in the "Yingzao Fashi", a building manual written by 1100 and published by Li Jie (1065–1110) in 1103.
