Confucius, a great thinker and founder of ancient Confucianism, said that he once said, "Review the past and learn the new." The reason is that people often read books only once. This way of reading can only understand the superficial meaning, but can't understand its internal meaning and more knowledge. On the surface, it is clear that the five strong men of Langya Mountain are extremely brave. The internal meaning reflects that justice will surely triumph over evil. * * * How many soldiers the producer led the PLA to sacrifice for today's happy day. As long as you read it again, you will find that the words used in this sentence are accurate. For example, the word "jump" shows the courage of the five strong men of Langya Mountain and their firm belief in serving the country. If you read it again, I am sure you will find more truth. Reading is like this again and again, from shallow to deep. I still read some books I didn't like when I was a child, but now I feel very different from before. Although it is a children's book, there are profound changes in writing and conception. I have benefited a lot from reading these books over and over again. The books are like this. There are still people who look at Kojiro from time to time, because he let me know that one should have lofty aspirations at all times.

"Reviewing the past and learning the new" is only five words, but it contains Qian Qian's philosophical thought, which teaches us how to read and learn, embodies the unique views of sage Confucius in teaching and educating people, and embodies the profoundness of Confucian culture and the profoundness of ancient civilization in China.
