Ke Yang, the owner of an antique shop, discovered a mysterious Qing Dynasty bronze mirror while collecting antiques in the countryside. The mirror surface was extremely clear and the back was engraved with the inscription "See the past and never forget the way back." He was attracted by its unique charm. After the bronze mirror was hung in Ke Yang's bedroom, he began to have nightmares about women from the Qing Dynasty. At the same time, he found that his reflection in the mirror occasionally disappeared, and even a woman wearing Qing clothes appeared. . . .
