“The Silk Railroad” is a first-ever co-production by CGTN and National Geographic. In this episode, British historian Sam Willis and CGTN journalist Li Qiuyuan take a visit to the Qin-Han pathway, part of the ancient Silk Road, which stretched onto places like Rome and beyond some 2,000 years ago. They find out why Shu brocade was once as expensive as gold and have a try to make their own pieces. The full episode of Chengdu will be broadcast on CGTN this Sunday.
