I found myself back in Shanghai not really to sightsee, but more to retrace my better half's steps during the time she lived here. To tell the truth, I never really gave Shanghai much of a chance, since I've never spent more than 2 days here, nor with anyone who actually knows it well. Aside from the record-setting pollution on the final days (even worse than Beijing, and actually made international headlines), it struck me as a highly liveable and cosmopolitan city. Not very surprising considering its GDP per capita is now surpassing many Western nations.
Things to call out - strolling the narrow pedestrian streets and art galleries of Tianzifang, pushing through crowds in the Yu Yuan Garden and neighbouring bazaar, revisiting Heping Rd (much cleaner now), and catching river crabs while in season.
