Zuojiang Huashan Rock Art Cultural Landscape are an extensive assembly of historical rock art that were painted on limestone cliff faces in Guangxi, southern China over a period of several hundred years at least. The paintings are located on the west bank of the Ming River which is a tributary of the Zuo River.

The main painted area along the cliff has a width of about 170 metres (560 ft) and a height of about 40 metres (130 ft) and is one of the largest rock paintings in China.

The paintings are believed to be between 1800 and 2500 or between 1600 and 2400 years old. The period of their creations hence spans the times from the Warring States period to the late Han Dynasty in the history of China. Many of the paintings are thought to "illustrate the life and rituals" of the ancient Luo Yue people, who are believed to be ancestors of the present-day Zhuang people and inhabited the valley of Zuo River during this period. However, recent carbon dating suggests that the oldest paintings were executed around 16,000 years ago whereas the youngest are around 690 years old. - in: wikipedia
