As the climate changes throughout the year, so does the Tibetan clothing. In spring and summer, Tibetan people generally wear a short shirt of cotton or white silk inlay brocade inside, with a large left and a small right front part, and wear a robe sewn by cotton and wool with round collar and wide sleeves (called Chu Ba in Tibetan). Then use a colorful belt (about 2 meters long, about 20cm wide seven-color striped wool long belt) to tie Chu Ba in the waist. The two sleeves are crossed and tied at the back of the waist, forming a bag at the waist for carrying things. The trousers are wide around the waist, crotch, and bottom. And the boots are short and the hat is felt. In autumn and winter, the labor clothes are all made of leather or artificial fleece. Chu Ba is also made of wool or sheepskin. Wear a leather cap with ear protectors, and high boots or self-made leather shoes.
