It's a very loving and poignant, powerful movie between a husband and his wife who has amnesia from a traumatic brain injury.
His endurance and trys and failures of fighting for those memories, especially her
memory of recognizing him!
It's 1hr 49min long. Starring Chen Daoming, Gong Li, Zhang Huiwen (playing their daughter). It's a great movie worth watching. English subtitles.
