Zeng Guofan's lewdness was famous in the first half of his life, but he was dedicated to holiness, but he cured his color heart to some extent. This method is to record his lust in his diary, even because he scolded himself badly in his diary. Zeng Guofan used this method to spur himself, and his lust improved a lot. In his diary, he seldom mentioned his lust.

Zeng Guofan, the minister of arms stocks during Sun Yat-sen's period, left a very good impression on future generations, whether he was a man or an official. Some people even think that Zeng Guofan is a saint close to Confucius, but Zeng Guofan, who is worshipped by the world, had many shameful things when he was young, for example, he was extremely lewd at that time.

Young people are full of energy, perhaps because Zeng Guofan once molested a friend's concubine at a party. The princess's graceful figure and beautiful facial features fascinated Zeng Guofan. Because he didn't restrain himself, he openly molested his friend's concubines and let his friends know. For this reason, the two broke up in discord and never talked again. After returning home, Zeng Guofan was very ashamed of what happened at the wine table, so he recorded this scene in his diary, in which he also called himself a shameless and dirty scum.

Whenever Zeng Guofan has erotic thoughts, he keeps them in his diary, and he often reads them to encourage himself to quit. Over time, Zeng Guofan's diary rarely mentioned his records about women. This is precisely the beginning when he began to divert his attention and stop having erotic thoughts. Later, Zeng Guofan really had no idea about beauty. Perhaps it is this self-discipline that makes Zeng Guofan an admirable saint.
