Tibetan residential dwellings are first constructed with mud walls, which are then partitioned into several rooms using wooden planks. The lowest level of the house is typically used for livestock keeping and storing fodder, cow dung, and other materials. Living, sleeping, cooking, and furniture placement are all concentrated on the second floor. In most cases, poorer households have only two stories, with the roof leveled off using compacted earth—where, during the autumn harvest, people would traditionally thresh grain directly on this surface.Sun-dried green teais dried here.
