【正确答案】On True Friendship As the saying goes, one of the most beautiful qualities of true friendship is to understand and to be understood. And there is a similar saying in Chinese culture that it's enough if you have a friend who knows you well. Both of the sayings tell us that mutual understanding is the basis of true friendship. For one thing, friends are people who can listen to each other. We all want to be understood in this intensely competitive society where people are prone to be faced with constant pressure and misunderstanding. Likewise, our friends also want to be understood and get support from us. Mutual understanding is what friends are for. For another, only those who can understand each other and share their interests and ideals can become true friends from whom you can get support and courage; otherwise, you will find yourself helpless when you are really in need. In short, mutual understanding is the most cherished quality of true friendship. As a result, we should select our friends carefully.
