Moving to Dalian?

Hi I have been looking for teaching jobs and have seen some adverts from Dalian schools. At present I am living in Chengdu and it has been great but I need a change. I don't speak much Chinese at all (I know I am quite embarrassed about it) so will this be a problem in Dalian as I hadn't heard about this city before now.

So can I get info on Dalian what kind of city is it, are there ex-pats, what is it like in the summer and winter and any other tips or advice? Also can anyone recommend reputable organisations to teach English for an experienced teacher.

I would appreciate any advice thanks.
