Big antiques market in Putuo. The two-story space is dingy, grotty and stinks of cigarette smoke, but it's packed to the brim with every kind of weird curio and dubious "relic" from the past couple of decades to the past century or more. Assuming any of it's real. As at any market, expect to haggle with hostile vendors, and don't walk in unless you know what you want and how much you're willing to spend. A big flea market takes over the central plaza on Fridays.
