An opening ceremony for the Xuanquan Posthouse World Cultural Heritage Site, Dunhuang city, Northwest China's Gansu province, took place on April 29.

The 1:1 restored Xuanquan Posthouse, Xuanquan Posthouse display center, Xuanquan streets and markets and other formats near the world cultural heritage site welcome tourists with authenticity and style.

They vividly showcase the postal system of the Han Dynasty (206 BC-AD 220) and the prosperous scenes of the ancient Silk Road over 2,000 years ago, where envoys and merchants traveled endlessly.

The Xuanquan Posthouse was one of the important posthouses established by the government of Han Dynasty in the Hexi Corridor area of the Silk Road. It shouldered the important mission of postal transportation and receiving envoys and merchants and was in use for over 300 years.

There's been a large number of Han Dynasty bamboo slips – narrow strips of bamboo used for writing in ancient China – and various cultural relics unearthed on the site, bearing witness to the history of cultural and commercial exchanges that took place between the East and the West.

In 2014, the site was listed on the UNESCO World Heritage Site "Silk Road: Chang'an-Tianshan Corridor Road Network".
