Rites of Zhou
This text, "The Artificer’s Record", is a description of craftsmen’s techniques that includes two sections on city construction. It is a late addition to the "Rites of Zhou" () one of three ritual classics canonized during the Han. The "Rites of Zhou" is a blueprint for governmental administration divided into six offices representing Heaven, Earth, and each of the four seasons. The section for the "Offices of Winter", a bureau charged with the oversight of public works, was lost sometime before or during the Qin to Han transition. During the Western Han, "The Artificer’s Record" was added as a replacement.
