Shiguang Dailiren Fanwai Pian: Biwu Zhaoqin

Liu Siwen has spent years trying to win permission to marry Ouyang, but her father, a formidable martial artist, refuses to accept an outsider into the family unless Liu can defeat him fairly in a duel. Love is not the problem. Liu's hopeless fighting ability is.

He turns to Cheng Xiaoshi and Lu Guang, whose unusual work at Time Photo Studio can send them into the past through photographs. What begins as a clever attempt to give Liu the advantage soon becomes a delicate operation in which a single mistake can alter events. To bring the couple together, Cheng Xiaoshi must survive the duel, follow Lu Guang's instructions, and resist his own tendency to improvise at exactly the wrong moment.
