This kind of street is common in China. Some may be longer and sell more variety of souvenir and have more eating stalls. Saishang Old Street could be one of the shorter ones. You will finish it from start to end within 10 minutes if you have no interest of buying anything. For tourists, it is the place where they can finish the smaller notes before returning home with handful of souvenirs for relatives and friends. It's crowded and seemed to be popular there.
