The novel begins with a case of missing children, and tells the twists and turns of a retired policeman who, driven by his sense of responsibility and justice, insists on tracking the case until the truth is revealed. Enthusiastic, kind and honest people have recovered the long-standing folk culture and national traditions while seeking for the missing children. The sun is turning around on this land, and people’s lives are turning upside down.

Starting from the Tibet Trilogy, Fan Wen has dedicated his writing to the contemporary life and rich ethnic culture. In his latest book Sun Down, the writer focuses on grassroot people and community officers’ endeavours in alleviating poverty.
