The study of any subject should start with the history of the subject. The postgraduate entrance examination for philosophy is divided into three parts: China's philosophy, western philosophy and philosophy. I recommend you to start with Feng Youlan's History of China Philosophy. If you have enough time, you can of course read Ren's History of China's Philosophy and China's Outline of Philosophy. If you want to have a deeper understanding of some philosophical issues, you can look at the works of Xiong Shili, Li Zehou, Xiao Jie's father, Lao Siguang, Mou Zongsan, Feng Qi and others. These are all domestic philosophers, some of whom are modern Chen Lai. Of course, these people have dabbled beyond the scope of China's philosophy. From the beginning, it was definitely easier to read books written by Chinese people than books written by westerners. In philosophy, Machiavelli is the most basic, and then you can read biographical books. Of course, if you are interested and confident, you can look at the complete works of Marx and Engels. Xizhe, there is a textbook, History of Western Philosophy, published by Renmin University of China Press, which is used in my university. Hegel can't help but mention Xi Zhe. At that time, our teacher said that if you know a little logic, you can teach some teachers in this university, hehe! Others, such as Kant, can also learn from the history of western philosophy. I suggest that it is unnecessary to spend too much time and dig too deep if you don't test the direction of western philosophy. Because it's really too deep to dig in a short time. . . That's all, I hope I can help you! By the way, if you want to take the postgraduate entrance examination, you must first determine the school and direction, because each school has different books for the exam, so you must read these books carefully first. Wish the postgraduate entrance examination go smoothly!
