Garment collars in hanfu are diverse and come in several shapes, including jiaoling, duijin, yuanling, liling, fangling, tanling. Some forms of collars were indigenous to China while others had been adopted from the Hufu of other non-Han Chinese ethnic minorities and/or from the clothing worn by foreigners.

A yuanlingshan is a type of round-collared upper garment in the traditional Chinese style of clothing known as Hanfu; it is also referred to as a yuanlingpao or a panlingpao when used as a robe. The yuanlingshan and yuanlingpao were both developed under the influence of ancient Chinese clothing, known as Hufu, originating from the Donghu people during the early Han dynasty and later by the Wuhu, including the Xianbei people, during the Six Dynasties period. The yuanlingpao is an article of formal attire primarily worn by men, although in certain dynasties, such as the Tang dynasty, it was also fashionable for women to wear. In the Tang dynasty, the yuanlingpao could be transformed into the fanlingpao using buttons.
