Yuan Zhilan attends a class reunion in place of her sister Yuan Zhihua, who recently passed away. While there, she reunites with her high school sweetheart and her story slowly unfolds as they communicate through letter writing.

Japanese director Shunji Iwai (All About Lily Chou-Chou) heads to China to cast a spell of romance and time in this charming, generation-hopping story of love letters, separation, and loss. Wonderful with actors old and young, Iwai spins a deliriously convoluted story juggling melodrama and comedy.
