Villagers help to protect Great Wall

Under the scorching sun, Wang Jihu and dozens of villagers clean dust and earth from a section of the Great Wall in Gansu province.

To help protect the ancient cultural relic, Wang and more than 50 other villagers are building a channel to catch floodwater.

Stretching 88 kilometers in Ximen, the section of the wall where Wang works was built during the Ming Dynasty (1368-1644). More than 400 km of the Great Wall can be found in Gansu.
