This is a good opportunity to learn or better your mandarin chinese speaking and writing skills. I studied here and met a lot of people who help you with what they can. Also the activities are fun and just the right environment to develop your mandarin skills and socialize with other students. The teachers are also very nice and offer you the best time overall in class and some other activities available. Their teaching material, techniques and methods applied have the clear understanding of the students mind and how to transfer the knowledge to the students and it also gives you the right motivation to keep practicing to improve. I have also a recommendation since you are going to be in Hualien how about doing some volunteering work and visit Tzu Chi abode, and take a look over there and other places to practice your chinese and immerse yourself in Taiwanese culture.
