Nestled in the center of Hong Kong, the neighborhood of Hung Hom is a study in contradictions. While the dead are transported to the nearby funeral homes, the living crowd its bustling streets. The affluent live in luxury residences towering over dilapidated buildings marked for demolition, while the poor sift through construction waste and trash for a meagre living wage. Capturing the ebb and flow of this urban district over a five-year period, Wong Siu-pong’s latest observational documentary provokes thoughtful discussion at a time when waste disposal has become a hot-button issue. 'Obedience' questions what is truly considered waste in this city.
