Liang Baizhou, who ran away from a Dunhuang ancient building family, became an ordinary courier in Beijing, determined to preserve the ancestral craftsmanship. An unusual delivery forced him to repair a piece of Qing Dynasty hanging flower door that even experts were unable to do anything about. His skills shocked everyone. From then on, his peaceful express delivery life was shattered and he was involved in the complex "Beijing Circle" composed of top collectors, industry leaders, and hidden forces. In the process of restoring precious antiquities that carry history and conspiracy, he not only has to face the pressure of his peers, the temptation of fame and fortune, and emotional entanglements, but he will also gradually uncover an old incident related to family origins, and find his own "craftsmanship" in the whirlpool of skills and humanity, inheritance and interests.
