This monument was written by Huairen, Shaman of Hongfu Temple, and Wang Xizhi, the general of Jinyou, and was erected by law in Beijing on December 8, the third year of Tang Chengheng (AD 672). Wen Zhugeshen, Wu Qiwei and Zhu Engraving. Running script, 30 lines, 85 lines, 86 words. Carve seven Buddha statues. The monument was originally in Hongfu Temple in xi 'an, Shaanxi, and later moved to Xi 'an Monument Forest. Preface to Collection of Wang Shengjiao is later than Yanta Chu Suiliang Book 19 years. The multilingual king answers questions, the crown prince writes answers, and the Prajna Paramita Sutra. It took Huairen 25 years to collect Wang Shu. Wang Xizhi, a beginner in calligraphy, traveled to famous mountains after crossing the river to the north, and saw traces of calligraphy such as Lisi, Cao, Zhong You, Liang You and Cai Yong successively, so he changed his teachers, cursive writers Zhang Zhi and Zhong You, and got a secret. Then he added the ancient method, changed the simple style of Han and Wei calligraphy, and created a beautiful and convenient modern style, which is true, solid and careless. First, Liang Wudi commented on his book cloud: "The words in the book" Xi "are bold and free, such as the sky in Yue Long and the tiger lying in the phoenix, so they have been treasured from generation to generation and always thought they were training." Li Shimin, Emperor Taizong of Tang Dynasty, said, "Only Wang Yi has made a detailed study of ancient and modern times and made a thorough study of the fine elements of seal cutting! Looking at the slow work and the fine work, it was beautifully cut and the haze was exposed. If it is broken, it will be connected, and the phoenix will be like a dragon. If you are inclined, you will get tired of playing. You don't know its end, but you are chasing it with your heart. This man is just the rest. What's the point? " Because of the emperor's love and advocacy, and the echo of ministers, and because of his charming and beautiful calligraphy style of "peaceful and ambitious, but far away from the breeze", it has indeed been respected by future generations, and it has been regarded as a "book saint" for thousands of years, and it is logical for calligraphy circles to regard it as a standard. Although the preface to the holy teachings is a collection of words, it lacks the combination of words. However, due to Huairen's meticulous skills and serious practice, he was able to fully display the artistic features of Wang Xizhi's calligraphy, which, in Amin Wang Shizhen's words, was "the first of the eight methods" and became the treasure house of Wang Zi. This tablet was interrupted after the Song Dynasty, and it was handed down from generation to generation with an unbroken Song rubbings. The handwriting was slightly fat, and the nib made the turning point visible. Wang Xizhi's exquisite brushwork and vigorous brushwork reveal the charm of "dignified and elegant, vigorous and graceful" between the lines, which is really difficult for later literati to achieve. When we study this position, we should first understand the laws of Wang Zi in the process of repeated reading. When we put pen to paper, we should exercise our pen power, appreciate its "hard bone" and "neatness" in bone strength, especially the copying of Lanting in Tang Dynasty, and make a stroke with muscle, bone, blood, pulse and flesh, and the traces of its stippling should conform to the pen gesture. At the same time, it must be understood that Wang Xizhi's success is due to his mastery and application of calligraphy techniques. On the other hand, because of his care for the mountains and forests, he is indifferent and elegant, so that in the process of pursuing the natural interest of calligraphy, he has never been obsessed with statutes, or his techniques have never been bound by statutes. This is quite enlightening for ordinary learners. Therefore, it is very important to keep calm and relaxed when learning Wang Zi's skills. How to master the "degree" between the two is also a problem that we must solve according to our own situation in the process of learning. Secondly, it is an important feature of Wang Xizhi's calligraphy that "it is flat when broken, and oblique when inclined". The preface to the holy teachings, which consists of words, has been greatly adjusted in composition and layout, but it was not written in one breath, so there are some shortcomings, that is, some words are not coherent enough and circulation is not enough. In this regard, we can pay more attention to the connection between upper and lower brushstrokes, and refer to Wang Zi's calligraphy posts, such as Preface to Lanting, Post to Mourn, Post to Clear Snow, etc. From this, we can feel and appreciate the wonderful layout of Wang Shu's essays, and then we can naturally glimpse the true meaning and grasp the overall style.
