Zeng Guofan is in an important position, busy with official business, and has been away for many years, so he can't always urge his children, so writing letters has become an important means for him to educate his children. Even if he works late into the night, he will find time to read his children's letters. Advocate the spirit of thrift in the family and oppose extravagance and laziness. Although Zeng Guofan himself ranks among the three public figures, he is always strict with his brothers and children. He never allowed his children to sleep late, in order to save money to buy fields, to wear fancy clothes, to scold servants and to despise neighbors. Educate the children at home to respect the old and love the young, respect their in-laws after marriage, and not bully others. At home, men have to sweep the floor and grow vegetables, and women have to cook and weave. When his wife and daughter lived with him in the Governor's Office of Liangjiang in Jiangning (now Nanjing), he stipulated that he would cook during the day and spin and weave hemp until late at night, every day. Zeng Guofan's daily diet is always based on one meat, without adding guests. It's even easier to wear. A green satin coat lasts for 30 years. Teaching by example is more important than teaching by example. Zeng Guofan is busy every day, from morning till night, never slacking off, setting a good example for his children. The main official documents are self-approved and self-drafted, and there are few fake hands. Blindness in his right eye in his later years still persists every day. He kept a diary until the day before his death.

Zeng Guofan educated his children not to be officials and get rich, but to read and understand. The shortest way to find a way out in feudal society is to be an official. At that time, bureaucrats' children wanted to squeeze into the officialdom by virtue of their power, but Zeng Guofan repeatedly told them: I don't want my children and grandchildren to be generals, and I don't want my children and grandchildren to be big officials. I just want to be a gentleman who has read a lot and understands reason. Those who are industrious, thrifty, self-disciplined, industrious and flexible are all virtuous people. Therefore, since the Zeng Guofan brothers, there has never been a general who led troops to fight in the Zeng family. Most of them have studied in famous universities in Britain, the United States and other countries, and achieved remarkable results. They became famous masters in the fields of education, science and technology and art, and made indelible contributions to the cause of human civilization and progress.
