     As it is known to us all,there are 55 minority groups in China,each with its traditional customs and

culture. Now let's take a look at the Tibetan Minority.    

     The Tibetan Minority groups live in Qinghai, Gansu, Sichuan and Yunnan Provinces. And the

highest ridge in the world -beautiful and mysterious Tibet is their major living place. As there are rich

grass in Tibet, most people live on raising sheep, goats, cattle and growing a special kind of plant called 

 Qingke. Because of unique climate, people often wear warm and comfortable boots in winter, and they

always wear robes (长袍)which are made of the fur of sheep.Often they take off one sleeve (袖子) of

the clothes in order to work easily and use them as warm quilts at night.    

Both men and women are good at singing and dancing. When they meet an important guest, they will

present him or her a Hada, a piece of long white silk cloth to show their respect. And they will also treat

the guest to a special kind of drink called Suyou Tea.    

     The Tibetan Minority has deep emotions. The people there are very warm-hearted and friendly.

They live freely and happily on the spacious grassland. Their history and culture are very important in

China, so we certainly should protect them, make them happy and let them receive great respect they

deserve.
