For 1,500 years, the stone Buddhas of the Yungang Grottoes have watched over Datong, silently witnessing the changing fortunes of the city in north China's Shanxi Province. Today, they're at the heart of an unexpected new trend. Gong Cuiying and a group of local women spend their days dressing miniature "Buddha dolls" in tiny, hand-crocheted hoodies. In a city once powered by coal, these women are weaving a new kind of future, stitch by stitch, proving that Datong's greatest resource has always been its creativity.
