The Rooftop (2013)

Gao and his friends are the happiest kids in the city of Galilee. Living on the rooftops of this bustling metropolis, sometimes life can be tough, but they still churn out songs all day, and dance under the stars at night. But when Gao meets his dream girl, a billboard beauty named Sian, fate takes him on a wild ride through the high and low parts of the town he loves.
