Useful. Tao Tao Du Yue is one of the few intensive reading classes I have seen in the market. Its form of class is to let you read by yourself after class and discuss with the teacher in class. The teacher's time is all yours. The reason why it is intensive reading is because it asks more questions and goes deeper. A deeper analysis and interpretation of the article will help to sort out the context of the story and analyze the personality characteristics of the characters and the world outlook and values of treating people. In fact, it is to think more and learn to read intensively.
