What are the elements of harmonious campus?

The first one I think is communication,because communication will deal with the differences between we and others。Next,a good attitude is in need,not only in studying,but the relationshlp among persons。Having a attitude will make us feel good and have a life。Last,these out-going characters are helpful,these will shorten the distantance between two persons。It can help us make a harmonious campus。These are my personal opinions。
