Smoke or no smoke, the weather was amazing!
I travelled all over the province.
Every day was sunny, warm (hot in the interior) and dry. The only rain was for about an hour one night when I was staying in New West (and even that was warm and had the strongest summer rain smell I have ever experienced. Noticed it while sitting in the house).
I bought a new camera for my trip (a Canon 80D) along with a telephoto lense. I took thousands of pics and videos. Just got home in Japan today so I am now starting the editing. There will be a massive wave of photo posts coming from me very soon
Enjoy your trip back to Shanghai.
