Generally, it is solved through HOAS (housing agency under the student union of Helsinki University). You have to hurry, don't wait for them to arrange, or you will have to wait for a long time. It is best not to rent a house by yourself. First, it is not cheap; second, the traffic is often inconvenient. HOAS occupies a large number of houses near railway stations and subway stations and rents them to students at half price.
Remember to clean regularly. HOAS will send someone to check it out. If the public area is not clean, they will send someone to clean it until it is cleaned for you. Others charge by the hour, which varies from 70- 120 euros per hour depending on the number of people. If you are too dirty, it may take five hours to wash it.
Eat something
Unicafe at school is enough for you to eat, and it's cheap. A meal costs 2.5 to 4.5 euros, and you will definitely be full, although it tastes ordinary. But this is not the price of lunch in China's first tier cities. If it's not too much trouble, you can bring your own food. Alexandria Learning Center can go to the kitchen and heat food in the microwave oven.
study
Don't just think that you are going there to study for a degree, and studying abroad is just for learning. You must take the initiative to communicate with teachers and classmates. If you don't talk, no Finnish students will take the initiative to talk to you. You should explore your own life circle and don't study in the library all day! Pay attention to efficiency! Ask the teacher questions you don't understand, and the teacher will be very happy. Most professors in Finland are very patient. Don't ask too many questions in class, which is impolite to other students. If you don't understand, you can ask the teaching assistant and visit the teacher's office hours. The school has free printing places every semester, which is enough for you to print what you have learned. If you can't use it up, please don't print cartoons or anything like that. In the past, some students in China did the same thing, which had a very bad influence.
social contact
This is really important. Active socialization can solve your single problem, work and study problem. Finnish students are really serious. They usually have nothing to be happy about, but they don't show that others hate you. So don't get me wrong, take their indifference as hostility.
