Hidden behind a quiet park in Yangpu District, this lively flea market runs every Wednesday, Saturday, and Sunday from 6am to noon. It’s a no-frills, open-air market where locals sell everything from vintage cameras and old newspapers to antique jewelry and Cultural Revolution memorabilia. Expect friendly bargaining, plenty of character, and a peek into old Shanghai. Come early, bring some cash, and be ready to dig for hidden treasures.
