If you live on campus and leave your parents, you can exercise junior high school students' independent ability, including independent living ability, thinking ability and problem-solving ability. People need to face many problems in their life, and how to solve them is to face them alone. There are many disadvantages, for example, you may not be able to eat your mother's cooking, and your diet is not as good as at home. If you are a girl, if your school is unsafe, you are easy to be invaded by bad people. If you are alone, you will inevitably need to make friends, and if you are not careful, you will easily go astray.
