This proverb comes from a wise concept, which is intended to emphasize that people must abandon old things before pursuing new things. In life, sometimes people are bound by inherent ideas, habits or materials and cannot embrace new possibilities. Only by abandoning the old shackles can we create opportunities for ourselves and accept new challenges and changes. This proverb also reminds us that when dealing with problems, we should have the courage and determination to let go of the past and welcome the future, and not be limited by the past, otherwise new opportunities will not come. In personal development and social progress, this idea of "the old will not go, the new will not come" is also of great significance, because only by letting go of old ideas and habits can we embrace innovation and progress and realize the sustainable development of individuals and society.
