Mandarin/Cantonese Classes in Koh Samui

Hello!


I am looking for a language school on Koh Samui that teaches either Mandarin or Cantonese but I'm afraid I'm not having much luck. I'm an ESL teacher and most of my students are Chinese natives and I feel like it would help me teach better if I could speak the language a little!


I'm also looking for classes to help me get a VISA for Thailand and I do want to learn a language but not sure how useful Thai is to learn in the bigger picture as compared to Chinese.


If anybody knows of a school that teaches Chinese and that could help with a VISA, please share!!


TIA.
