The earliest salt use is argued to have taken place on Lake Yuncheng, Shanxi by 6000 BC. Strong archaeological evidence of salt making dating to 2000 BC is found in the ruins of Zhongba at Chongqing. The historical records show that salt and iron monopolies often provided the bulk of state revenue, and remained important to state finance until the 20th century. The Discourse on Salt and Iron, written by Huan Kuan during the 1st century BC relates a debate on the state monopoly over salt and iron production and distribution.
