Cheongsam, the traditional dress of Chinese women in China and around the world, is known as the quintessence of China and women's national dress. It is one of the most gorgeous phenomena and forms in the long history of Chinese costume culture. Chipao was formed in the 1920s of the last century, and its origin can be traced back to the Shen Yi of the Pre-Qin and Han Dynasties. After the 1920s of the Republic of China, it became the most common women's dress and was identified as one of the national dresses by the government of the Republic of China in 1929.
