Costumes are not only the carriers of the spiritual features of the times and the social identities of characters, but also the embodiments of the spiritual temperament and moral characters. Referring to the costume regulations of the Qing Dynasty, old photos, and documentary materials, and combining the actual costumes and the spirit of the characters, a specific analysis is conducted on the costume shape, fabric, color, and other aspects of Yang Jinbi. This scheme focuses on presenting Yang Jinbi's image of the times and social image through the shape and fabric, to reflect the character's spiritual temperament and moral character like "a piece of unpolished jade carved into a fine piece" through colors, etc., and explore the fashion of folk costumes for men in the late Qing Dynasty.
