Based on:
Zeng Guofan attached great importance to the role of practicing calligraphy and reading in self-cultivation. Calligraphy is an indispensable part of his life. He once wrote in his diary: In recent years in the army, he didn't think much, but he kept waving his pen every day. In addition to writing and office work, he also learned a calligraphy without interruption. He devoted himself wholeheartedly to the bookshelf, and his brushwork kept pace with it. Ten years ago, the words in his chest could achieve today, which shows that thinking and learning cannot be neglected.
Zeng Guofan likes calligraphy very much. Although his level is not as good as that of Liu Wang and others, he is also unique and has certain ornamental value. He keeps a diary every day, which makes his calligraphy level higher and higher. When writing calligraphy, people need to concentrate on nothingness, which is obviously an excellent mental exercise.
His two sons are He Zeng, but they were born weak. He asked them to copy the words of Yan Zhenqing and Liu Gongquan. Because he thinks that Yan is vigorous and Liu is tough, practicing these two kinds of calligraphy often will subtly change the weak physique of his sons.
