Heze

Heze, formerly known as Caozhou, is the westernmost prefecture-level city in Shandong province, China, bordering Jining to the east and the provinces of Henan and Anhui to the west and south respectively. Caozhou was at the center of the Nian Rebellion during the 1850s and 60s. In August 1949, Heze was detached from Shandong and given to the experimental province of Pingyuan, but was later returned to Shandong just over three years later.
