History books recommend reading General History of the World and General History of China, which is the book with the most historical world outlook, followed by various history books such as Detailed Qin and Han Dynasties, Detailed Jin and Northern and Southern Dynasties. If the landlord has enough knowledge of ancient Chinese, he can also read Twenty-four History and Zi Tong Zhi Jian. There are also some books on historical research, which can also enlighten people's way of thinking, such as Chen's Lecture Notes on the History of Wei, Jin, Southern and Northern Dynasties and Wanli Fifteen Years.

Recently, I read two popular books on sociology and recommended them to the landlord: The Third Orangutan and Collapse were written by the same author named Garad Diamond. Very good. It can distinguish things you have never thought about from many things you are used to.

I can only upload one attachment. All the books I mentioned are electronic versions. If you need other books besides "Elaborate" series, please leave your email and I will send them to you.
