Caution leads to peace of mind, respect leads to physical strength, benevolence leads to pleasure, and hard work leads to reverence, which can basically summarize Zeng Shengren's point of view. In addition, from the evaluation of modern great men, we can see Zeng Guofan's wisdom, kindness and compassion, which is worth learning from later generations. His teacher's philosophy of "knocking out teeth and swallowing blood" is worth thinking about. As for his comments and opinions, there are many, too numerous to mention. You can search online. What's more, I suggest that if you have time, go and see Zeng Guofan's family instructions taught by Professor Libo in Lecture Room. They're great. You'd better listen to all of them and learn more about Zeng's thoughts and his charming personality.
