In a big city such as Shanghai, the Labor Arbitration Bureau is fair and mostly on the side of the employee. In general you cannot be fined so much money for leaving early - as mentioned above it is 1 month notice on a 1 year contract. In a small city, however, it could be more difficult. If you leave the country, no one is going to "come find you", that is certain.

I like the way that they have incorporated video into the site, a great idea for schools moving into the future:
