Certainly, for discovering China (it was the first time for me) and immersing yourself in it's deep and ancient culture, a good guide is required.
After reading a few reviews and wondering wether this would be the right option or not, I just decided to place my trust in Hutong school. Good choice.
To make a long story short, I spent 4 beautiful months with the school, its friendly personal and the people I met there. Teaching, activities, receptionists and co-workers are all helpful and kind, and the atmosphere good. You'll always find somebody to help you, to share a meal with or just to talk to. It was as well really quick to meet new people and make friends.
The lessons are efficient: their limited number of persons and their schedule (that you can change in case of need) allow you to practice and learn chinese in the right way according to your capacities. I highly recommend it.
I'll always have good souvenirs, and maybe to the next time!
Thank's to you guys.
