Song Zhuxi's half acre square pond was opened, and the sky was covered with clouds and shadows. Ask the canal to be so clear, because there is running water at the source. Last night, the river was full of water, and Meng Chong ships were a dime a dozen. It used to take a lot of effort to push it, but today it can move in the middle of water. This beautiful picture of natural scenery is refreshing. What is even more amazing is the reading method of the title and the feeling of reading this book. Suddenly, this beautiful artistic conception was sublimated and integrated with reading. It turned out that what Zhu, a great scholar, realized in praising reading, the carefree, clear and lively feeling in his mind was vividly depicted by the reflection of ponds and clouds. Why is his mind so clear? Because there is always new knowledge in books, like running water, which constantly supplements him. Zhu used these two poems to illustrate that life is the source of writing. Only by observing attentively can we find the source of running water, learn from it and be a conscientious person in life.
