Description : Small tea stalls along the river Brahmaputra, called Yarlung Tsang Bo in Tibet, give shelter to the traveler. Well insulated with a central oven, these stalls will serve a range of foods depending upon the proximity to major cities, but butter tea is universal and one's cup is never allowed to run dry. A woman who runs a tea stall poses with her relatives, who help her run the shop. Tibet. China.
