Confucius said, "If you can talk to others without talking to them, you will lose others. If you don't talk to them, you will make a slip of the tongue. If you know it, you will lose your words. " What does this mean? A person can be honest with him, but he is afraid of offending others, not being honest with him and sorry for others. Some people can't be honest with him. If you confess to him, it will not only waste, but also offend people. Therefore, a truly wise person should say it when it is time to speak. Do not lose people, do not lose words.
