what is the name of traditional chinese male clothing
Changshan A  changshan (help·info) (Chinese: 長衫; pinyin: chángshān; literally: "long shirt") is a traditional Chinese dress (or robe, long jacket or tunic) worn by men. In function, it is considered the male equivalent of the women's cheongsam (qipao). It is also known as a changpao (chángpáo 長袍, "long robe") or dagua (大褂 dàguà, "great jacket"). It was often worn by men with a magua or "riding jacket". These types of dress were widely adopted beginning under the Manchu (Chinese: 滿族) rulers of the Qing dynasty (Chinese: 清朝), who required that men in certain positions wear this style. It took more time for the majority of women to adopt the new style of qipao rather than hanfu (Chinese: 漢服).
Silk Silk's absorbency makes it comfortable to wear in warm weather and while active. Its low conductivity keeps warm air close to the skin during cold weather. It is often used for clothing such as shirts, ties, blouses, formal dresses, high fashion clothes, lining, lingerie, pajamas, robes, dress suits, sun dresses and Eastern folk costumes. For practical use, silk is excellent as clothing that protects from many biting insects that would ordinarily pierce clothing, such as mosquitoes and horseflies.
