I am a businessman who has stayed in China for four years. From an outsider to half-native people, i am familiar with all the places in Shenzhen right now. i can speak simple chinese, but it's not enough for me.
I emerged great interests in Chinese culture! So I took course in Hanbridge Mandarin school in Shenzhen. It gave me very good impression!!! The teachers here are nice and patient. I have learnt many things that I don’t know before. such as the story of Chinese spring festival, Mid-autumn festival...I sincerely introduce you www.hanbridgemandarin.com
I am sure you can learn what you want.
