2, that is to say, reading should be down-to-earth, and every concept theorem should be thoroughly understood, so that a thin book becomes thicker because of adding a lot of content, from thin to thick.
3, there is a more important step after this step, that is, on the basis of the first step, analyze and summarize, grasp the essence, grasp the whole, and achieve mastery through a comprehensive study. After such a careful analysis, we will feel that there are not many things that should really be remembered. This is a "coarse to fine" process, which can really improve efficiency.
4. Hua advocates that the first step of reading is "from thin to thick".
In other words, reading should be down-to-earth, and every concept and theorem should be traced back to the source and thoroughly understood. In this way, a thin book becomes "thicker" because of adding a lot of content, which is "from thin to thick"
