A good opportunity to know more about the Silk Road.

The "Landscape Map of the Silk Road", an imperial painting for the Jiajing Emperor in the Ming Dynasty ((1368-1644) ) is on show during a media preview of "Treasures of Time" and "Landscape Map of the Silk Road" exhibitions at Hong Kong Science Museum in Tsim Sha Tsui, Hong Kong, Dec. 6, 2018. The map, measuring about 30 meters long and 0.6 meters wide, was drawn on a silk handscroll. It named over 200 cities, ranging from Jiayu Pass, Gansu province, in the east, to Mecca, Saudi Arabia, in the west.
