If You Are the One (simplified Chinese: 非诚勿扰; traditional Chinese: 非誠勿擾; pinyin: Fēichéng Wùrǎo; literally: "if not sincere, do not disturb") is a 2008 Chinese romantic comedy film directed by Feng Xiaogang and starring Ge You and Shu Qi. The film has been very successful at the Chinese box office, and has become one of Feng's top grossing films to date, and has earned over ¥364 million (US$53.7 million) at the box office.
Qin Fen (Ge) returns to China in his late forties after many years overseas. He did not earn any type of degree while he was overseas. However, he is good with convincing others. He becomes a multimillionaire after selling an "innovative invention" to a high-profile (but foolish) angel investor (Fan). With his new fortune, Qin decides to put an end to his bachelor life and advertises online for potential partners to apply "if you are the one", that is, only if they are sincere.
