On a Harmonious Dormitory Life

Dormitory life is an indispensable part of college life. But sometimes the harmony in the dormitory can be disturbed in one way or another.

As is known to all, a harmonious dormitory life is important to college students and benefits all the members. On one hand, you can have a good rest and put your heart into study. On the other hand, you will have a good mood and enjoy being together.

There are several ways to create and maintain a harmonious dormitory life. Firstly, you have to evaluate your lifestyle and try to get rid of your bad habits, if there are any. Secondly, when an annoying situation arises, you'll just have to learn to tolerate each other and coexist. Thirdly, you'll have to share with each other and make good friends.

In conclusion, you should make every effort to build a harmonious dormitory life for the sake of good study and good life.
