Background: The Manchu (Manchu: manjU; Mollendorff: manju; Abkai: manju; simplified Chinese: Man Zu ; traditional Chinese: Man Zu ; pinyin: Manzu; Wade-Giles: Man3-tsu2) are an ethnic minority in China and the people from whom Manchuria derives its name. They are sometimes called "red-tasseled Manchus", a reference to the ornamentation on traditional Manchu hats. The Later Jin (1616-1636), and Qing dynasty (1636-1912) were established by Manchus, who are descended from the Jurchen people who earlier established the Jin dynasty (1115-1234) in China. Manchus form the largest branch of the Tungusic peoples and are distributed throughout China, forming the fourth largest ethnic group in the country.
Context: The early phase of Manchu clothing succeeded from Jurchen tradition. White was the dominating color. To facilitate convenience during archery, the robe is the most common article of clothing for the Manchu people. Over the robe, a surcoat is usually worn, derived from the military uniform of Eight Banners army. During the Kangxi period, the surcoat gained popularity among commoners. The modern Chinese suits, the Cheongsam and Tangzhuang, are derived from the Manchu robe and surcoat which are commonly considered as "Chinese elements".  Wearing hats is also a part of traditional Manchu culture, and Manchu people wear hats in all ages and seasons in contrast to the Han Chinese culture of "Starting to wear hats at 20 year-old" (Er Shi Shi Guan ), . Manchu hats are either formal or casual, formal hats being made in two different styles, straw for spring and summer, and fur for fall and winter. Casual hats are more commonly known as "Mandarin hats" in English.  Manchus have many distinctive traditional accessories. Women traditionally wear three earrings on each ear, a tradition that is maintained by many older Manchu women. Males also traditionally wear piercings, but they tend to only have one earring in their youth and do not continue to wear it as adults. The Manchu people also have traditional jewelry which evokes their past as hunters. The fergetun (fergetUn), a thumb ring traditionally made out of reindeer bone, was worn to protect the thumbs of archers. After the establishment of the Qing dynasty in 1644, the fergetun gradually became simply a form of jewelry, with the most valuable ones made in jade and ivory. High-heeled shoes were worn by Manchu women.
