History carved in stone

History has shaped the faces of many Chinese mountains, but the shapes of faces chiseled into Kongwangshan are China's most historical.

The 110 images etched into a 17-m-wide, 9-m-high cliff in Jiangsu province's Lianyungang city are the country's earliest known cliff carvings.

It is estimated they were engraved more than 2,000 years ago - about 300 years before those of modern-day Gansu province's Dunhuang Grottos. But it wasn't until the 1970s that archeologists rediscovered the site, which local residents had until then largely taken for granted.
