Possibly Shanghai’s last standing secondhand book market (and its longest running), Wenmiao aka Ghost Market got its name from the glory days when thousands came at dawn and you could only make out their ghostly silhouettes. Although not as crowded as it used to be, it is still a great stop for incredibly cheap novels, periodicals, catalogues, brochures, children’s books and foreign language books (though you’ll have to dig for those). Apart from that, things get nostalgic with old photos, diaries and comic strips. Haggle hard and make your mind up quickly.
