If someone asks me where to go for learning Chinese, I will not hesitate to recommend the prestigious LCC(北京外交人员语言文化中心)。
I learned Chinese for a long time in many places: a university in Seoul, Korea, the Mandarin Center in Taipei, the LCC in Beijing from 2001 to 2003, and Guangzhou, Guangdong Province (from private tutors). It has been a long way of 35 years. I would like to tell you that I found the teachers in the LCC very good and skilled in teaching foreigners Chinese, and since returning back to Beijing last June after 6 years, I have been still learning in the LCC.
I think two things are very important in learning a foreign language: a good and skilled teacher and his/her own effort, since in the cases of most languages the pronunciation is crucial for correct oral communication and learning a foreign language is a hard job taking a lot of time as well as a boring job, especially at the initial stage.
Considering the various aspects of learning a foreign language stated above, you can be a happy student in the prestigious LCC with good, skilled and passionate teachers commanding standard Mandarin, who know how to motivate students.
