2020.8.13 summary

I made up the supplementary question this morning, and found that the speed has slowed down after too long. Compared with the previous one, it is a big step backward. Find time to practice again. Then I spent most of the remaining time reading Liu Rujia's book plus some examples and some exercises from the book. Indeed, after careful consideration of the sample questions and understanding all the status, the exercises are basically the extension and depth of the sample questions, and by the way expand the thinking. When I read this book before, I found it too difficult. The first thing I felt was that I really didn’t understand it. At that time, I just put this book aside and didn’t read it much. Now I took it out and saw I didn’t know what he said before slowly. He told us how to design the state and solve the problem. He basically didn’t involve any “terms”. Tomorrow and the day after tomorrow, strive for independence and do more questions and broaden your thinking.
