Tibetans pay great attention to etiquette. In daily life, they bow to their elders and peers in different ways. Buddha statues, pagodas, living buddhas, and elders who pay their respects all kowtow. Offering Hada is the highest etiquette for Tibetan guests, expressing warm welcome and sincere respect to the guests. Tibetans make zān ba from highland barley, and drinking butter tea and highland barley wine is the staple food of farmers and herdsmen. At a holiday wedding or a gathering of many people, drinking usually means toasting the respected elders first, and then toasting clockwise in turn. There are six burial methods for Tibetans after death, the most grand one is tower burial, but only the living Buddha and some lords can enjoy tower burial after death.
