This book mainly records the most important stage of Zeng Guofan's life in the form of letters, with a wide range of contents. He can reveal his feelings in ordinary trivial life, and there are beautiful words between the lines, which makes me very moved!

The way to cultivate one's morality tells me to cultivate one's morality and reflect. You must learn to be cautious when things are smooth sailing, so as not to be in danger of subversion soon. We should have awe, learn to be prepared for danger in times of peace, and don't get carried away because of temporary success and forget the truth that fortunes depend on each other. He also said that people can't be without defects, and there is nothing perfect in the world. Flowers bloom and fall is the law. Where there is prosperity, there is decline, and doing things for defects is the most perfect way.

Zeng Guofan's way of doing things tells us that "not greedy for money", "not faithless" and "unnatural". Cultivating people's cohesion through calligraphy can just give up the lazy habit. Practicing calligraphy doesn't happen overnight. Writing a good text requires long-term practice. Practicing calligraphy can be calm and sincere to get rid of your impetuous atmosphere.
