Just thought I'd say something as an ex Hutong School student: I'm happy with it!!
Lanaier, you're right about competitors try to slur each other! There aren't many competition laws here (Starbecks coffee anyone?) so business is normally carried out with good will. And also, you really need to check out any company you want to come out with. But go beyond "Scam?" websites and check if they have a facebook, linkedin, etc presence as well as the local media reviews.
From my point of view, I had a great time and got what I wanted - a job, new language, living in a new country and a great twist to my career! I'm loving Beijing!!
Oh, and Leena is Belgian, I'll take the piss out of her English for this!
