A great trade route connected China to the West: the Silk Road. No place in China better illustrates the value of that route than Dunhuang, site of the Mogao Caves, grottos carved into a cliffside which hold the largest collection of Buddhist art anywhere. In Gansu province, Dunhuang was the site of the Jade Gate, where the main road left China into the lands beyond.   Nathan Cherry of the Silk Road History Podcast helps tell the story of these caves, their city, and the route, starting with the expedition of Zhang Qian, China's Lewis (or maybe Clark?) who first traversed into the unknown.   More stories follow: the son of immigrants who translated the sutras, the daughter who went to war, the crown prince who saved countless artifacts.   The caves are remarkable; the town is too, nestled against giant sand dunes at the edge of the desert. To eat, try Lanzhou Beef Noodle Soup, the perfect breakfast, if you like soup for breakfast - Westerners might find this a perfect dinner instead.   Selected Sources: Keay, John.
