Yizhou (Chinese: 宜州; pinyin: Yízhōu), formerly Yishan County (宜山县), is a district under the administration of Hechi City, Guangxi Zhuang Autonomous Region, People's Republic of China. Yizhou is located in the northwest of Guangxi on the Long River in an area noted for its magnificent karst formations. The limestone karst formations dot the district and surrounding country and several rivers cut through the landscape. The district of Yizhou has several hundred thousand inhabitants. The surrounding countryside is home to a number of ethnic Zhuang villages. The economy is centered on sugar production, with a British-Chinese jointly run sugar processing plant nearby. The countryside surrounding Yizhou is similar in appearance to the tourist Mecca Yangshuo, located in the east of Guangxi. While
