This film was pulled from showing in China because:
As it gained popularity at home, the government appears to have gotten nervous. “Return to Dust” was suddenly dropped from cinemas in mid-September, despite being licensed to screen for longer. “Everyone knows there are lots of poor people,” says Mr Lei. “But the government doesn’t want Chinese people to see too much of it.” President Xi Jinping would like the arts to project “positive energy”. To that end, before the film was pulled from cinemas, the state added a postscript that straightened out its depressing ending. With the help of the government and fellow villagers, the message read, Mr Wu’s character moved to a better house.
