Thanks for posting the pictures of your visit to Tianjin. They are great and I enjoyed getting the chance to see the town again.
I was there working in November and December 1993. Unfortunately I didn't get too much time to see the sites but got to know my coworkers very well. Its so much better to see a new place from the locals' point-of-view rather than as a tourist viewing from the outside. Perhaps I'll get back there so day.
