What can I do with Tibetan beggars?

Religious beggars are an accepted part of society in Tibet. Giving money or food to a pilgrim is considered an act of merit, donations of one or two yuan(Chinese money) are appropriate. Notice if the beggars are the old men and women who dress in shredded, bulky clothing, while the younger ones may have a monkey on a chain, a spectacle of great interest to the Tibetans. These beggars are professionals, having less meritorions intentions than religious pilgrims. Just wave them off as the locals do if you don't want to give anything.
