During college, you can take a class on holidays or weekends. After you have a foundation, after you graduate, you can prepare for the exam and find a German language school. After passing the examination, you can directly apply for a "language+study abroad" visa. If you have been studying in China for 1000 hours, you can also apply for a "study abroad" visa directly after taking the DaF/DSH exam, but the application time is before 10/5/7 15 every year, and you can wait until the new semester starts in April.15.
Kassel, Germany is a city in West Germany, located in central Germany, one hour's drive from Frankfurt/G? ttingen. At present, universities there do not charge tuition fees, and language classes are very cheap. I am in the DSH preparatory class of Suez Language School, and the tuition fee is only 400 euros /200 hours. The teachers there are all very enthusiastic. Students can also pay tuition for half a year. There is also a good language school, but later their tuition has gone up a lot, which is much more expensive than this. Not many students go to China, but there are more aborigines who receive government salaries.
