Over the course of six years he traveled to the Huangtu Plateau in Datong, and in 2001 he published a book of photographs documenting life there. Almost all the landscape photos in the book show the distinctive eroded valleys of the plateau—deep rifts that the elements have cut into the silt-like loess soil. The rifts, some of them up to 100 meters deep, can be seen everywhere on the plateau and are familiar scenes for the people who live there. But they have a strange fascination for visitors from abroad, few of whom have ever seen anything like them before.
