Country no. 6 on the Silk Route is Yarkand in China. Mind you the distances are so great you would think the region that Yarkand sits in was a country in itself!
Yarkand was a great trade centers on the Great Silk Road, and was famous for its markets, where goods from all over the world could be bought. In modern times it is still a major transport hub for this region of China.
The Bazaar unlike other Bazaars is not within city walls but streets on and around Mausoleum of Ammnaishan and the Altun Mosque.
