Trouble Maker

Original title: 蠟筆小小生

Directed by Kevin Chu

A meek, middle-aged schoolteacher is put in charge of a class of trouble makers. Unable to withstand the torments they put him through, he runs away to a Shaolin temple. At the temple, he studies martial arts under the guidance of an old master. With his new skills, he returns to school and whips his misbehaving students into shape.
