Secondly, if you want to go deeper, you can look at our philosophy. Tao Te Ching is a good choice. But be sure to buy something annotated or translated (such as Moral Progress published by Chongwen Bookstore). Without annotations, it may be difficult for Mr. China to translate.
Then you can read the history of western philosophy. But this book should not be read first.
At ordinary times, you can look up all kinds of philosophical celebrities to understand their theoretical systems and thoughts, such as Kant, empedocles, Aristotle, Descartes, Marx, Freud, Heidegger and so on.
To understand them, you can buy some compilations about them, such as The Wisdom of Aristotle and The Wisdom of Freud (China Film Publishing House).
When you feel that your philosophy has accumulated deeply enough, you can read Metaphysics (note that it was written by modern people, not Aristotle, and don't listen to high school teachers saying that metaphysics is not good, and westerners have completely different attitudes).
The above books are only for amateurs who love wisdom but can't cope with the exam. But you must believe that China's philosophy is undoubtedly the most autocratic and thinnest in the world.
