The history of Pingwu goes back over 1,700 years. In 108 CE, the
Eastern Han established Guanghan County, which was ruled from present day
Wen County. Beginning in the 3rd century CE, a number of kingdoms belonging to the
Di tribe were set up in and around Pingwu County. In 280 Pingwu County was first established. The name Pingwu originates from the name of the previous Yinping () and Guangwu () counties. In 347, Pingwu became part of the
Eastern Jin. By the 6th century, the Di kingdoms saw their power wane, and much of the area surrounding present-day Pingwu County was integrated into the
Yarlung dynasty. Despite this, the area of contemporary Pingwu County was not occupied by the Yarlung dynasty during the 7th century, resulting in a linguistic identity more akin to that of the Di tribe. == Geography and climate ==
