Wen Zhiming wrote thousands of words, and at the rate of ten books a day, books made great progress. I have lived in books all my life, and I have never hesitated, or simply answered people, and I have never taken pains again and again, so the older I get, the more subtle I am.
Wen Zhiming copied thousands of words, with ten copies a day as the standard, and calligraphy made rapid progress. He has never been careless in writing all his life. Sometimes, if you write back to someone a little unsatisfied, you have to rewrite it over and over again, and enjoy it. Therefore, the older you get, the more refined your calligraphy becomes.

Another calligrapher who practiced calligraphy diligently in ancient China was Wang Xizhi. Wang Xizhi was a great calligrapher in the Jin Dynasty 1600 years ago, and was known as the "book saint".
In Linchuan District, Fuzhou City, Jiangxi Province, it is said that Wang Xizhi, a great calligrapher in the Eastern Jin Dynasty, washed his pen and inkstone. Wang Xizhi began to practice calligraphy at the age of 7 and worked hard. 17 years old, after reading his father's previous calligraphy works, he practiced hard every day and washed his pen in the pool after practicing. Over time, he turned a pool of clear water into black.
Later, Ceng Gong admired Wang Xizhi's reputation and made a special trip to Linchuan to mourn Mo Chi's body. Wang Sheng, a professor of Chinese studies (official name), asked him to write a note about "Mo Chi in Wang Youjun", so Ceng Gong wrote this famous essay "Mo Chi Ji" based on Wang Xizhi's anecdote.
