五個小孩的校長 (Little Big Master) (Blu-ray release 2015-8-20) is one of the best Hong Kong movies this year. This is a true story about a teacher who accepts an incredibly low salary and goes to teach a countryside kindergarten with only 5 students, otherwise that kindergarten will be closed down and the poor children cannot receive education.
The cast is really good. The lead actress gave one of her best performances, and the adorable kids performed exceptionally well too.
Many incidents depicted in the movie really happened, although they are not restricted to the real life counterparts of the five kids depicted in the movie, e.g. a real estate company building a sand wall to enclose the home of a poor family to force them to move out, the teacher being persuaded to join a profit-oriented tutoring school, and a kid saying she does not want to graduate, etc.
