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).
Simplified Chinese characters A small group called Dou Zi Sei (T:導字社; S:导字社)/Dou Zi Wui (T:導字會; S:导字会) attempted to introduce a special version of simplified characters using romanizations in the 1930s. Today, however, the traditional characters remain dominant in Hong Kong.
