Language schools in China for foreigners?

Hi! I am a huge language-learning lover, and Mandarin Chinese is one of the next on my bucket list. Besides Mandarin, I am also widely interested in the cultures and minorities populating China, and if I succeed in learning Mandarin, I will consider learning more languages of that region. Specifically, I have always admired Tibetan language and culture. So I wonder if there are any language schools for the Tibetan language in Chinca, either for foreigners, or in the Chinese language for locals. Would appreciate any information!
