The Guanzi is an ancient Chinese political and philosophical text that is named for and traditionally attributed to the 7th century BCE philosopher Guan Zhong, who served as Prime Minister to Duke Huan of Qi. At over 135,000 characters long, the Guanzi is one of the longest early Chinese philosophical texts. The Han Dynasty scholar Liu Xiang edited the received Guanzi text circa 26 BCE, containing a wide variety of material from many different authors over several successive centuries, largely associated with the 4th century BCE Jixia Academy in the Qi capital of Linzi.
