Why did Zeng Guofan let his son concentrate on practicing calligraphy?

Zeng Guofan said to his son: "After this, you can make less progress. Go in again, get sleepy again, endure again, get excited again, and there will be a day of prosperity and progress. If you don't learn Chinese characters, everything will become extremely difficult and difficult. If you can make sense, you are a hero.

According to the contents of Zeng Guofan's family instructions, this paper classifies them from the aspects of treating people, managing the army and politics, maintaining family style and maintaining body and mind, and makes detailed comments, translations and evaluations on them.

As the saying goes, "a lot of skills can't maintain a person's livelihood", that is to say, skills should be specialized. I dug many wells, but there was no water to drink. This is a careless mistake at work. In any case, your younger brothers should devote themselves to one subject, such as Jiu Ge's determination to practice calligraphy, and other aspects need not be completely abandoned. It's just that when you practice copybooks every day, you must never lift your spirits, and you can get in touch with them at any time. As for Brother Si Liu, I don't know if you have a hobby of studying wholeheartedly.
