Newman Tours, who run a range of walking trips around the city, have launched this gangster tour, which takes in a bunch of the places where the opium kingpins of 1930s Shanghai lived, loved, made and lost their fortunes. Equal parts fun and factual, as well as family-friendly, the tour lasts about two hours and there's an option to go shooting at a local rifle range afterwards. Phone to reserve a place: 138 1777 0229. Full info at www.newmantours.com
