Recommend one to see.
Hao Ming's historical novel Zeng Guofan is a novel, but it reproduces the magnificent history of the late Qing Dynasty with a very broad scene. This film can understand the situation of Xianfeng from the end of the Qing Dynasty to nearly half a century, especially the beginning and end of the Taiping Heavenly Kingdom Movement. Highly recommended, a very good book.
There are other films about this period, such as The Biography of Cixi, Li Hongzhang by Levin, China's Elegy-Shi Dakai, Monk Qin, Lin Zexu, The Last Emperor, Zuo Yihetuan and Taiping Heavenly Kingdom. It's been too long to remember clearly.
From the time after the Republic of China to the time before the founding of the People's Republic of China, we can read Fan Keming's Biography of Zhang Xueliang, Biography of Zhou Enlai, The Story of 1911, Heroes of the Republic of China, Hundred Years of Storm, etc. I don't know much about the northern warlords in that period, and I'm sorry I can't help you.
Actually, you can search online. Generally, there are many biographies of important people in history and other books. If you want to see someone, you should find them. I have an electronic version of Zeng Guofan's book. If I can't find it, I'll leave an email and send it to you. Take your time. There are many books. Reading more books is good. I don't have much time to read them now. It's quite comfortable to read books every day after settling down, hehe. .
