Xie Xisi, a calligrapher in the Yuan Dynasty, once commented on this post: "The book" Wen Fu "is a volume, and the calligraphy in the Tang Dynasty is vigorous and powerful, with the style of Jin people, but I only look at this volume. Although Sui monks are wise and brave, they still hate being too charming and neat. Loneliness is a sigh in this book. " Yuan Zhao Mengfu spoke highly of this, saying, "Lu Jianzhi's calligraphy and prose were authentic in the right Tang Dynasty, and the person who was good at calligraphy in the early Tang Dynasty was called Ou Yu Chuxue. As far as calligraphy is concerned, he is the fourth son. However, there are few traces of the world, and those who know the ancient times like it "(Postscript of Zhao Mengfu's Wen Fu). Zhao Mengfu studied this post, from which he learned the brushwork and structure of Jin people and benefited a lot. Sun Chengze wrote a postscript in Chinese ink, saying, "Zhao's calligraphy has been powerful since then, and people seldom see Si Jian's book, so they don't know what to say. "
