Frequent visitors to Tibet can distinguish people from different regions by noting costumes and dialects. People from agricultural regions dress in woolen home-woven gowns; those from the grassland wear sheepskin. The men from Chamdo wear huge tassels of black or red silk, which had been used in the old days for protection in battle, while the Lhasa residents are more stylish and modern. The Tibetan language has four major dialects: Lhasa, Tsang (Shigatse and Gyantse), Chamdo, and Amdo.
