Banknote books are both tangible material preparation and a writing technique. You can also develop a good habit of reading and thinking. Why not? However, there are also pitfalls, as Zhou Zuoren reminded, "Learn "I am sick". "Wen Zhi Gong" needs to have its own value standards and aesthetic standards, otherwise, who won't take the banknote? Who can't make it into an excuse for laziness or even plagiarism. The reason why the ancients talked about this time "Banknotes", of course, is sent with feelings. People reading books today are generally too floating, such as dragons and water, not as ancient people dive and play. This is because there is too much to read now, no time, so I have to read ten lines at a time. They all "know". Another thing is that before the May Fourth Movement, we respected the ancients too much; after the May Fourth Movement, we despised the ancients too much. We all want to open up the world, and there are no ancients before. It is too late to write our own books. Banknotes for others' books? Inconsistent with the text is:. ['Must be a book with information and aesthetic value.', 'Thinking while writing notes.', 'Reading books today is not as careful as the ancients.', 'Only by studying the method of ancient banknotes can we overcome the prevailing trend.']
