Producer Li Fang revealed that the earliest idea of filming Broken Bridge originated from September 2065438+2009, when he and Li Yu went to Panzhihua City, Sichuan Province for filming.

Li Fang recalled that on the way, Li Yu suddenly had an idea "She told me at the time that she wanted to make a movie about women's revenge."
