Who was born dull, but made unremitting efforts to become a "half saint in the history of China"?

There are two kinds of people in the world, one is plain but successful through unremitting efforts, and the other is successful with his own talent and intelligence. Zeng Guofan belongs to the first kind. He was born dull but made unremitting efforts, and became a half saint in the history of China. Speaking of saints, what are the standards of saints? Ordinary saints have made many indelible contributions to future generations, both in culture and politics. In the history of China, I think there are three great saints, the first is Confucius, the second is Wang Yangming, and the third is Zeng Guofan.

When it comes to Zeng Guofan, most people will think of his great achievements, but they never thought that he was born dull and made these achievements through unremitting efforts. He used to make jokes when he was a teenager, and even thieves made fun of his stupidity. The thing is, thieves came to his house to steal things, but I didn't expect Zeng Guofan to come back from the private school soon and recite the simple articles he learned during the day. Unexpectedly, it may be that he has a bad memory, or it may be that he is stupid. He has been unable to recite this simple article for dozens of times. Wash your face when you are sleepy and come back to recite this article. However, the thief had no choice. The thief could recite this simple article to him, but Zeng Guofan could not, so Zeng Guofan was laughed at by the thief. Since that incident, Zeng Guofan has made up his mind to work hard. Although he is stupid, he can succeed through hard work the day after tomorrow. Yes! He succeeded, and he succeeded in making himself a half saint in history. I admire his efforts and his sense of responsibility. Knowing that disciple Zuo was gossiping behind his back, he resolutely helped. In Zeng Guofan's eyes, everything is based on national interests. He is the only one who dares to say such things when recommending sages. If this person is incompetent or has a problem, please remove me from my post. No one in the crowd can do it like him. He can take this responsibility without wasting his efforts. For some reason, he became a saint.
