'So Long, My Son' traces the lives of two families over three decades of social, political and human upheaval in China. Following the loss of a child in a tragic accident, their paths separate. Destinies ebb and flow, and fortunes are transformed under the impact of a country's changing face. Yet even as their lives diverge, a common search for truth and reconciliation around the tragedy remains. But sometimes it can take a lifetime to say farewell. Wang Xiaoshuai's acclaimed drama chronicles people and a society in full transformation - in which human relationships and the tumultuous evolution of a nation are inevitably and inextricably intertwined.
