A photo exhibition now running at the Cultural Palace of Nationalities in Beijing unfolds a panoramic view of the natural wonders and cultural depth of Sunan Yugur autonomous county in Zhangye, Gansu province.

Sunan, located on the northern stretch of the Qilian Mountains, boasts grassland scenery and ecological diversity and is inhabited by several ethnic groups, predominately the Yugur people.

Sunan has witnessed the crisscrossing of different cultures throughout its history. The exhibition, running through April 3, celebrates Sunan's past and present as an example of preservation and promotion of rich ethnic traditions, environmental protection and rural revitalization.
