Studying Chinese is definitely a great way to meet friendly and open-minded people from all over the world. As far as the student life at Omeida goes, the summer students are generally livelier and tend to stay for a couple weeks or more. As winter hits, the scene becomes a little quieter and more studious, with overall fewer students, who tend to stay for longer periods of time.
Since I was studying for five months, I decided to only take three classes per day, as I wanted a chance to review what I'd learned and I didn't want to burn myself out, but there is an intensive option for six hours per day or specialized classes to gear students up for the HSK (Chinese proficiency exam). In our classes, we covered plenty of useful grammar structures, vocabulary and common expressions that came up a lot in daily conversation, with writing and reading forming the basis of the homework.
There were also organized weekly trips to nearby mountains and rice terraces, and cultural lessons in cooking, traditional music and calligraphy.
