There are two solutions to "review the past and learn the new" One is to "review the past and learn the new": review what you have learned and gain new insights from it; Secondly, "review the past and learn the new": on the one hand, we should review the stories of laws and regulations, on the other hand, we should strive to acquire new knowledge. It may be more complete to combine these two solutions: within our ability, read the classics as widely as possible, think about their meanings repeatedly, and review what we have heard regularly, so as to gain experience and understanding; And strive to absorb new knowledge; In this way, we can expand the field of human knowledge, and closing the door can also give the sages the meaning of the wisdom era. The integration of the old and the new, the integration of the ancient and the modern, can be called "reviewing the old and knowing the new."
Review the old knowledge you have learned frequently, and you will have new experiences and discoveries. You will gain more, you will know more than others, so that you can become someone else's teacher in some way.
In life, everything, every sentence has many aspects. Different people have different understandings. Maybe you can only understand one of them for a while, but when you have experienced more and learned more, you may have a different understanding and experience when you go to see it again. Life is so many sides. When you don't understand a word, do you choose to abandon or ponder? When you delve into it many times, you will have a different experience.
When we are busy with a stage of things, we take advantage of the temporary busy time and look back at the dribs and drabs, only to find that we can't be slaves to work. Learn to think and summarize, and make your work full of persistence and growth.
