"From thin to thick" means that reading should be down-to-earth, tracing the source of important words, being good at trying to figure out between the lines, studying the author's way of thinking, trying to figure out the author's writing intention, and extending the knowledge of the article from multiple angles through divergent thinking. The purpose of "reading thick" books is to cultivate readers' ability to integrate and learn from others.
When our knowledge has accumulated to a certain amount, we should "slim down". We should also have our own thinking and distinguishing ability on the knowledge we have learned, get rid of the rough and the fine, get rid of the false and keep the true, grasp the main essential things in general, outline the essentials, clarify the context, establish the framework of the knowledge system, internalize it into our own things, simplify the complex, and thin the book from thick to thin, so as to improve efficiency.
