Before drawing the knowledge tree, we should have a detailed description of it.
The knowledge tree should be hierarchical. For example, a knowledge tree is like a traffic map of China.

Harvest map: theme; The first layer is divided into three branches: main content, learning comprehension and writing methods; The second layer is to deduce the meaning of the paragraph from the main content, the key sentences and feelings from the study of literature, and the beautiful words from the writing method; The meaning of the third layer can be deduced from the meaning of the layer or keyword.
