Heart refers to inner integrity, and pen refers to font integrity.

The original meaning of "the mind is regular and the pen is correct" means that if the mind is upright, then the font in the pen is also upright. ? Liu Gongquan is famous for his achievements in calligraphy, and his "pen admonition" of "regular mind and correct pen" has also been passed down as a much-told story by the world.

Emperor Mu Zong once asked Liu Gongquan how to write calligraphy well, and Liu Gongquan replied, "Use a pen in your heart, and your heart is regular." If your character is not high, you can't drop ink.

Because of Mu Zong's laziness in political affairs, Liu Gongquan used books as a metaphor for political affairs. On the one hand, he explained his attitude towards calligraphy creation, on the other hand, he skillfully remonstrated with the spirit of calligraphy art. Since then, the theory of "correct mind and correct pen" has been spread to future generations and has become one of the ethical standards of calligraphy.

The so-called word is like a person. In fact, works of art such as calligraphy, literature and painting all reflect the author's character and cultivation to a considerable extent, and also reflect the author's thoughts and feelings.

It is precisely because of Liu Gongquan's resolute and noble sentiment and character accomplishment that his vigorous and upright books shine on the paper. Later generations not only value his calligraphy skills, but also admire his character, so that calligraphy and personality are immortal.

Extended information:

Liu Gongquan is a summarizer and innovator of regular script style. On the basis of studying and inheriting the regular script styles of Zhong You and Wang Xizhi, he read modern calligraphy, learned from Yan Zhenqing, absorbed his own new ideas, and created his own unique "Liu Ti" regular script, which was a model for later generations and became one of the outstanding representatives of "Tang Shu Shang Fa".

His handwriting is even, balanced, thin and hard, and he follows Wei Bei firmly. His stippling is crisp and beautiful, with strong bones and tight structure. "The book is expensive, thin and hard, and the spirit is clear." Compared with the face, his regular script is slightly even and thin, so it is called "Yan Jin Liu Gu".

since the Yuanhe period in the Tang dynasty, Liu Gongquan's reputation has become increasingly high. Tang Xuanzong especially cherished Mo Bao of Liu Gongquan. He once called Liu Gongquan to the front of the temple, and the military commander made Ximen Jixuan hold an inkstone, and the Tang Dynasty envoy Cui Juyuan took a pen. Liu Gongquan wrote the cross of "Mrs. Wei's brushwork in Wang Youjun" on a piece of paper with a real book.

On a piece of paper, he wrote eleven words: "The Family Method of Yongchun Temple with a thousand words of true grass" in running script; On a piece of paper, I wrote the words "how can the predicate help others?" Xuanzong gave him silverware such as brocade and bottles and plates. And let him write a thank-you note, regardless of the real book or cursive script. ?

At that time, the ministers' family erected a monument for their ancestors. If the inscription written by Liu Gongquan was not available, people would think it was unfilial. Moreover, Liu Gongquan's reputation spread far and wide overseas, and when he went abroad to pay tribute, he specially prepared money to buy Liu Gongquan's calligraphy. Tang Wenzong once praised his calligraphy, even the rebirth of Zhong You and Wang Xizhi.

The calligraphers such as Yan, Liu, Ou, Chu and Yu in the Tang Dynasty are still the first choice for people to learn calligraphy, especially the standard of a set of regular script established by Liu Gongquan, which is still an example for people to learn today.

Liu Gongquan made outstanding contributions in the reform and development of calligraphy art, which summarized the development of calligraphy in the Tang Dynasty and laid the foundation for the development of regular script as a whole.
