Qian Daxin has made great achievements in various fields. He is a generation of Confucian scholars and "an art that a Confucian should have without learning and refining". Poem couplets handed down from ancient times were originally official scripts, and China's paintings and calligraphy paid attention to learning from them. Copying the previous pen and ink is to absorb the nutrition of traditional culture, but after all, it is to accumulate one's own flesh and blood in other people's words, and it is absolutely lifeless to blindly steal the bones of the ancients. And Zheng Gang stood on the shoulders of others, reaching for the clouds, turning grass into silk, and becoming a splendid world. Therefore, his calligraphy couplet is ingenious in every word, vivid in brushwork, full of vigor and vitality, quite flying, extremely elegant and full of emotion. This kind of calligraphy is not limited to stagnation, madness, desolation and cynicism. It is an open-minded, atmospheric and peaceful book of the mean. This kind of skill is really like seeing him standing at the edge of a book, splashing ink and sweating through the back of the paper, and the paper suddenly presents a "generation of Confucianism" style. I think that only by thoroughly understanding the essence of literature and books, and deeply understanding the wonderful principles of people and books, can we write the strength of this famous association. Words are like people. This kind of nature is purely from his indisputable state of mind, seeing through the generosity of clouds and water, and his elegant and modest mind.
