Video-streaming giant Youku released award-winning Hong Kong director Peter Chan’s latest short film, Three Minutes, on Feb 1.

Adapted from a true story, the movie centers around a brief reunion during Spring Festival between a train attendant and her 6-year-old son, during the train’s three-minute stopover at a station in their hometown.

Chan, known for the 1996 classic romance Comrades: Almost a Love Story, says the new film was shot entirely using an iPhone X smartphone, during a preview screening in Beijing just before the movie's online release.

Other than the main storyline, the short film also features sequences of still images showing the joyful faces of people as they are reunited with their families during Spring Festival.
