The official history is so vast that even Sima Guang claims to be "illiterate", so he wrote "Learning from the Same Experience" for future generations to learn. In the Republic of China, there was a man named Cai Dongfan. He wrote a set of books called "Popular Romance of China in Past Dynasties", which tells the story of each generation in chronological order, from Qin Dynasty to the Republic of China. It was not a general bestseller at that time, but it was still worth reading.
