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).
Ivory The Chinese have long valued ivory for both art and utilitarian objects. Early reference to the Chinese export of ivory is recorded after the Chinese explorer Zhang Qian ventured to the west to form alliances to enable the eventual free movement of Chinese goods to the west; as early as the first century BC, ivory was moved along the Northern Silk Road for consumption by western nations.[11] Southeast Asian kingdoms included tusks of the Indian elephant in their annual tribute caravans to China. Chinese craftsmen carved ivory to make everything from images of deities to the pipe stems and end pieces of opium pipes.[12]
