Photo taken on July 21, 2013 shows workers setting up catwalls at Yumenguan, an old city of northwest China's Gansu Province. Yumenguan Pass was once a key pass of ancient China on the historical Silk Road. The famous ancient Silk Road, which served as a corridor for trade and cultural exchanges between Asia and Europe dating back to 2,000 years ago, was inscribed on the World Heritage list at Doha, capital of Qatar on Sunday. Jointly submitted by China, Kazakhstan and Kyrgyzstan, the application for adding part of the millennium-old trade route to the UNESCO list was approved by the World Heritage Committee which convened its 38th session in Doha.
