Does anyone have any stories in history about calligraphers who studied hard before becoming famous?

The story of Wang Xianzhi, the son of the sage of calligraphy, Wang Xizhi, who practiced calligraphy has been a story through the ages. Wang Xianzhi was influenced by his father since childhood and practiced calligraphy with his brothers. In terms of talent, he is indeed superior to ordinary people, but what is even more extraordinary is his hard work.

There is a large vat in Wang Xianzhi's study room specially designed for him to grind ink. In the spring and autumn, Wang Xianzhi had used three large tanks of water in the blink of an eye because of his hard work in practicing calligraphy. Wang Xianzhi planned to ask his mother to comment on the work he wrote with the last pool of ink, so he excitedly left with the word "太" in his hand. However, he soon discovered that he had missed the word "Tai" a little bit. When I returned to the study, the inkstone was already dry, so I had to go to my father to explain the reason.

Wang Xizhi took the pen and put the last stroke on "big".

Wang Xianzhi turned to his mother, but her mother said: "I used up three tanks of water to practice calligraphy, and only one thing is like Xizhi." Wang Xianzhi knew that his kung fu was still far from enough, so he worked harder to practice calligraphy, and finally became the master of calligraphy. A great calligrapher as famous as his father.
