Cheng Yu-chieh wrote and directed this story of a woman whose broken family history leads her down an unexpected path towards self-acceptance. Chang Ching-yang (Sandrine Pinna), nicknamed Yang Yang by her friends and family, was born to a Chinese mother (Yu Tai-yan) and a French father, but her parents divorced when she was a baby and Yang Yang has never met her dad. 20-year-old Yang Yang is a gifted athlete who runs track, and her best friend Xiao-ru (Her Sy-huoy) is a fellow runner as well as the daughter of her coach (Chu Lu-hao). When Yang Yang's mother marries Xiao-ru's father, at first she's delighted -- Yang Yang finally has the father she's always wanted, and her best friend is now her sister. But love changes all that when Yang Yang falls for Xioa-ru's boyfriend Shawn (Chang Ruei-jia), and their clandestine relationship drives Yang Yang and Xiao-ru apart. Yang Yang gives up athletics to follow a new dream as an actress and fashion model, and she finds herself exploring a side of herself she's never cared to acknowledge when she lands a role playing a woman who is partly French and searching for her long-lost father. Yang Yang was an official selection at the 2009 Berlin International Film Festival.
