Dalian is a lovely city to work in. Very clean, not so much pollution, very green and great facilities. The two times I had cause to have need of the police during my time there they were helpful, supportive and courteous.

For a Westerner, Dalian offers a lot of home comforts, some great restaurants and an eclectic social scene.

If you can get a job there, go for it! But jobs there are few and far between as it's such a popular location to live and work.

I have friends in Hangzhou and they love it there. I've visited myself and found it to be a charming place. In fact had I not moved to Dalian, Hangzhou would have been a major consideration for me.

In regards to the OP, get yourself to the closest embassy and explain your situation. You should never go to any foreign country, especially one as corrupt as China, without information about the location of your nearest embassy, an open return ticket and at least enough cash to buy you a way home.
