同甘共苦与朋友不仅同喜乐，而且共忧愁，帮助朋友解除困难，这才是交友之道，为人真诚表面上说些好听的话，心里却不是那一回事，伪装，说谎，这种行为是使友情破裂的最大原因。为人要真诚，有话当面讲，不做小动作，这是交友的第一步。批评有据批评要有客观依据，避免武断， Sharing happiness and suffering with friends is not only a matter of joy, but also a common cause of sadness and helping friends to relieve difficulties. This is the way to make friends. To say good things on the surface in good faith is not the same thing, disguise, and lying, this kind of behavior is friendship. The biggest cause of rupture. To be honest with people, to have words spoken in front of you, not to do little tricks, this is the first step in making friends. Criticism is based on objective evidence and criticism to avoid arbitrariness.
