What kind of hair does a Dai woman wear with a small black bowl in her hair?

The headdress of the Dai people.

Elderly Dai women wrap their heads with white towels. Middle-aged women keep their hair long and tie it on the top of their heads, and wrap their heads with various colored gauze scarves. Young girls also wrap their heads with gauze scarves. Girls and young women braid their hair in the same style as in mainland China. Only during festivals, girls will tie their buns slightly to the left at the top and decorate them with hairpins, flowers, etc. When young women wear their hair in a bun, if their hair is not long enough, they put a stocking on their hair to increase the length and tie it into a bun.
