Kuodi Zhi
Kuodi Zhi, translated as Comprehensive Gazetteer or Comprehensive Land Records, is an early Tang dynasty survey of Tang China's geography and administrative divisions. It was compiled by Li Tai, Prince of Wei, a son of Emperor Taizong, with the help of imperial scholars including Xiao Deyan. It was completed in 641/642 AD.
The original work comprised 555 volumes, but most have been lost. During the Qing dynasty, scholar Sun Xingyan published the 8-volume book Kuodi Zhi jiben, a collection of the surviving fragments. In 1974, Wang Hui published a revised and expanded version of Sun's work entitled Kuodi Zhi xinji. In 1980, He Cijun published Kuodi Zhi jijiao.
