It is reported that Chen Shan of the Southern and Northern Dynasties wrote in his New Theory of Lice: "You should know the difference when reading. Go in at the beginning and come out at the end. See xian Si Qi, this into calligraphy; Very useful. It's calligraphy. I can't get into the book, I don't know the intentions of the ancients; If you can't publish a book, you will die in words. If you only know the difference, you have to do your best to study. "
The meaning of this passage is to know what you have learned when you are reading. Advance is to read into the book and master the essence of the book; Out is to jump out of books and be able to use book knowledge flexibly to solve practical problems.
