1- The directory is very important. Use the table of contents together with the year: mark the year and divide the times next to the table of contents to simplify some important information. Take the Ancient History of China (Gundam 1840) in senior high school as an example: the book can be divided into Stone Age (primitive society), Bronze Age (slave society) and Feudal Age (which can be divided into several different periods) through the catalogue. For example, in the Shang Dynasty in the Bronze Age, the words "Simuwe, human sacrifice system, moving the capital to Zhou Wang" were written. When you open the catalogue and see these words, you will think of the political and economic system, etiquette and funeral system, the state of the country's territory and surrounding forces and the reasons for its demise. For example, if you mark the seal of the Zhou Dynasty (1046-77 1, 770-476, 475-22 1), you will know that it is the Western Zhou Dynasty (Jing Tian system, enfeoffment system +0). Actually, look at the table of contents before reading and mark some important years on it. You can generally know most of the contents of the book through the catalogue. After reading each chapter, go back to the table of contents and recall the contents of that chapter. 80% of that chapter can basically be recorded. Read it two or three times more, so don't memorize it.

2- Examples of comparative study Comparing the Qin Dynasty and the Sui Dynasty, we will find that: a- Both dynasties were unified after a long period of division and war (this is related to the reasons for reunification), and the time for dual reunification was short. B—— Political and economic measures that were beneficial to the development of later generations in both dynasties (Qin —— unified measurement, writing books, abolishing the system of enfeoffment, setting up counties, Sui —— creating the imperial examination system). C- the reasons for the demise of the two dynasties are very similar (nothing more than heavy military service, large-scale projects, etc. , arouse the peasant uprising, and eventually perish). D—— After the demise of the two dynasties, a relatively strong dynasty (Western Han Dynasty and imperial examination system) appeared.

3- Some important times must be remembered: from 2070 to 22 1 (slave society), from 22 1 to 2 19 (Qin and Han Dynasties), from 220 to 589 (Three Kingdoms, Jin and Southern Dynasties) and from 589 to 907 (Sui and Tang Dynasties). (Note: I drew the above years from memory, and there may be small deviations in some years, please understand)

4- Film projection method. This is what I used to do in junior high school and senior high school: I spend 20 minutes before going to bed to quickly scan what I learned that day (I scan what I learned this week every Sunday for no more than 25 minutes). After lights out-close my eyes, I will recall what I saw in my mind and try to recall what I saw in 15 minutes. If I really can't remember, I won't think hard-to ensure sleep. ! ! After getting up the next day, quickly scan what you can't remember, which is easy to deepen your impression. It may be a bit difficult, but few people in our class learned it at that time. )

5- To put it bluntly. The chronological development of a directory is like the trunk and main branch of a big tree. Those literature, art, customs and personal achievements are just leaves hanging on different branches of the tree. The trunk and main branches of the big tree have come out, and those lobules have hung up (the age should be right). I haven't read history books for five years after the college entrance examination. I still remember about 75% of those historical knowledge (the rest may be recalled soon with some hints). I hope these methods suit you, hehe! ! !
