Chinese is not an easy language to study so it is especially important to have the right conditions for that. Omeida is located in Yangshuo near Guilin so studding here lets you enjoy the peace and quiet of a small town, surrounded by amazing green mountains.
The staff here are super professional and classes' size is very small so the lessons are very personal. I spent here 4 weeks to polish my basic Chinese and I have had a very good time here. volunteering with the Chinese students who study English had given me a chance to get to know better different people from all over china.
I would recommend coming here if you want to study Chinese properly for the summer or a long period of time (some students come here for several months).
