What are the advantages of China becoming a German citizen? How to become a German citizen?

If you have the ability, you'd better apply for a German company and work in Germany. You can apply for permanent residence after three years, which is the so-called green card (compared with German nationality, you just lack the right to vote and stand for election, and all other benefits and social security are the same). It is relatively easy to apply for German nationality when studying in Germany and graduating, but now it is a bit difficult to apply for German nationality by other means, mainly due to the limitation of years! After so many years of experience, the German Immigration Bureau has also summed up some relatively safe schemes to limit behavioral factors purely for solving identity problems.
