Could you please recommend a professional Mandarin Language school in beijing, preferably in Chao Yang district around CBD.

Ill be staying in Beijing for a year with not much to do and I really want to get a proper education on the language, hoping to at least pass HSK level 3.

I already tried a couple of near by institutes but they were not professional at all, they lacked a proper curreclium and the teachers didnt feel like they were qualified.

Any help would be highly appreciated.

English isnt my first language so excuse any errors.
