Being a happy foreign teacher in China is a great thing. I'm so glad that you find teaching at New Century English School in Dalian to be so satisfying. Congratulations on having found such a kind-hearted employer whose staff are so helpful. Be thankful for what you've got there, and stay put. You have painted such a rosy picture for us that I reckon you should go on teaching there for ever. If you choose to move on, you'll most likely be disappointed. Take my word for it. But what you say sounds almost too good to be true. Even so, I'll give you the benefit of the doubt, though that could be a big mistake on my part!
