Another flick shines light on the problems faced by the elderly

Hot on the heels of A Simple Life (2012) and Happiness (2016), another art-house film is portraying the aging population struggling with sickness and loneliness.

The Song of Cotton, adapted from Chinese American novelist Ha Jin's novella A Pension Plan, was previewed on Sunday and will be released across the country on Nov 4.

An America's National Book Award winner, Ha wrote A Pension Plan in English and translated the short story - featured in his 2009 book A Good Fall - into a 10,000-character Chinese version.
