Guangzhou Jiangnan Avenue North is the earliest professional wholesale and retail market for cheongsam dresses and wedding dresses in Guangzhou, with a large number of professional merchants. Cheongsam, also known as robe, is the traditional dress of women in China and even in China, and is regarded as the quintessence of China and the national costume of women. Cheongsam was formed in the 1920s. Some scholars believe that its origin can be traced back to the deep clothes in the pre-Qin and Han dynasties. Although there are many controversies about its definition and time, it is still one of the most splendid phenomena and forms in China's long-standing costume culture. Cheongsam became the most common women's dress after the 1920s.
