Rock paintings at the Zuojiang Huashan site in Guangxi Zhuang Autonomous Region.

A group of rock paintings dating back over 2,000 years in south China's Guangxi Zhuang Autonomous Region was included into UNESCO's world heritage list on July 15, 2016.

The Zuojiang Huashan site, covering over 6,621 hectares, is home to more than 1,900 well-preserved drawings on the face of the Huashan mountains along the Zuojiang River, Chongzuo.

The brownish red paintings depict the sacrifices of the Luoyue people, ancestors of today's Zhuang ethnic minority, during the Warring States Period (475-221 BC) and East Han Dynasty (25-220).[China.org.cn]
