Changshan

In traditional Chinese dress, a changshan (simplified Chinese: 长衫; traditional Chinese: 長衫; pinyin: chángshān; literally "long shirt") is the male equivalent of the women's cheongsam (qipao). It is also known as a changpao (chángpáo 长袍) or dagua (大褂 dàguà).

The Mandarin Chinese word changshan is cognate with the Cantonese term chèuhngsàam, which has been borrowed into English as "cheongsam". Unlike the Mandarin term, however, chèuhngsàam can refer to both male and female garments, and in Hong Kong is frequently used for the body-hugging female garment rather than for the male changshan. The Hong Kong usage is reflected in the meaning of "cheongsam" in English, which refers exclusively to the female garment.

A similar Burmese garment, called taikpon eingyi (တိုက်ပုံအင်္ဂျီ) which is also a jacket featuring mandarin collars, is part of formal attire for men at weddings and other formal functions. However, taikpon eingyi is much more form-fitting than the changshan, with sleeves that cut off at the wrist and typically made of silk cloth.
