Lifetime achievement

Wang Xiaoshuai's latest film charts the lives of two parents who struggle to overcome the sorrow of losing their only child through decades of change in China, Xu Fan reports.

When director Wang Xiaoshuai was shooting his latest film So Long, My Son in the Inner Mongolia autonomous region, there was a moment during one scene when he couldn't hold back his tears as he sat behind the monitor.

The scene depicted an elderly couple who were sweeping their son's tomb many years after an accident caused the death of their only child.
