We arrived in Shanghai this morning on the overnight train. For a hard sleeper, it was a surprisingly comfortable journey. We were in a compartment with six bunks, and mostly slept between lights out at 10pm and arrival at Nanjing just before 7. The toilets, however, were pretty disgusting... We got to Shanghai at 11ish, after passing lots of towns and cities with high rise buildings.
In Shanghai, we've walked along the Bund with its European-style buildings and view of the skyscrapers in Pudong and visited the Yuyuan gardens. This evening we went on a boat down the river, with both sides impressively illuminated. Definitely time for bed now though!
