How to immigrate to Germany? Germans are very exclusive. Will they be excluded?

Speaking of xenophobia, it is inevitable. Accent is a factor. For example, some cities and regions in China also have feelings of exclusion (foreigners), and you can look down on people by listening to their accents. Not to mention a few simple sentences for foreigners who can't speak standard or fluent German. It is not easy to express your meaning clearly. Do you still want to communicate freely with others? Without three or five years of hard work, it is really impossible to learn German. Just imagine that the communication between people will widen the gap, and over time, it will become a habit, and the chances of improving German will not increase because of the increase in time in Germany. Therefore, my point is that if you don't come to Germany to work or study, and you don't like drinking beer or are not crazy about football, you should not come to Germany, otherwise, you are likely to get mental depression.
