Personally, I suggest you find your own professional classmates in the university. When you first arrive in a foreign country, you are in a strange place and there are many people in the society. Don't think that Europe is a pure land! There are four advantages to communicating with students of the same major: first, can you communicate in German, Flemish and French (Belgium has three official languages), because you have the same professional knowledge, richer and more focused topics, and it is no problem to use English;

Second, it must be helpful for your study;

Third, while learning languages and majors, we should also learn about European society as soon as possible, especially laws and regulations. The research in this field should start with the rules and regulations of universities;

Fourth, young students are simple and easy to make friends. I am naturally more interested in international friends.

As for what you said, "How can I teach my friends with them ...? What kind of girls do you like? " It's hard to answer. But one thing is certain: Remember, your advantage is that you come from China and know China culture. Your weakness is that you are not, and it is difficult to become a real European. So in a word, you will be respected if you are from China, and you will be favored by westerners if you are from China who are good at learning western science and culture. Good luck!
