German diplomas contain a lot of gold, but it may be because of Germany's low-key personality that German universities are not very high in the world rankings.
If you want to study in Germany, you must first understand German. Of course, if you want to take an international course, you can use English. Moreover, you don't have to say the degree of German yourself, but you must have at least 800 hours of proof and pass the dsh exam or testdaf of a school before you can apply for a German university. If you want to apply for a language class first and then take a language test in Germany, you must also have a 400-hour certificate. However, reading a language in Germany is expensive and time-limited, so it is recommended to finish reading it in China before coming out. Then you have to take your language certificate (proof of class hours and test scores) and your contents and scores during your study at school to go to aps in Beijing to apply for certification and audit (usually just send it over). When they are ready, they will give you an exam about your professional knowledge and your mastery of German during school. After you have successfully obtained the aps approval certificate, you can send your application form and various materials (study, language, aps certificate, etc.). Go to the school you want to apply for (each school has different requirements for application materials, so you should go to their website to see what else is specific). Once you receive the admission notice from the school, you can send it to aps in Beijing with your passport, and they will help you apply for a visa. The deposit is about 7000 euros. You need to open an account with Deutsche Bank in China and deposit it. Then you can register a good school in Germany, find a good house and then go to the bank to activate it, and then you can use the money inside (of course, there are restrictions on withdrawal), mainly to ensure your life in Germany. Then what needs to be handled in China is the insurance during the period in Germany, which needs to be handled in aok or tk, and needs to be reactivated after arriving in Germany.
The cost of living in Germany is related to your city. You can plan according to 500 euros a month, so much is usually enough. But you have to control how much. Tuition is also related to the school. Generally, it costs about 500 to 1500 euros a semester, and there is also a registration fee of 100 euros. In most places, there is also a semester entrance fee. However, these can't be determined until you learn German well and start applying for schools.
