The Huashan rock art landscape in southern China, close to the border with Vietnam, is a remarkable UNESCO World Heritage site. Thousands of images are painted on river cliffs across more than 80 locations stretching 260 kilometers (162 miles). They depict people, musical instruments, boats, animals, weapons and many other figures, and date back at least 2,000 years.
