Desc: Zui hou de Bang Bang: Directed by He Ku. With He Ku. At the beginning of the reform and opening up, the unique geographical environment of mountain city Chongqing gave birth to a special industry - Bangbang Colony of Mountain City. Over the past thirty years of climbing hills and carrying heavy loads, hundreds of thousands of Bangbangs have not only carried away the years soaked in sweat, but also their own era. At the end of year 2013, several hunched figures were about to bid farewell to the disappearing industry. A retired colonel picked up a stick and began his pursuit - glory and awkwardness, hardship and helplessness. Their lives need no evaluation, and their stories are worth remembering.
