36. What is "Qianbei Brand"?
A: The Qianbei School is the predecessor of the Qing Dynasty tablet school. They are mainly good at writing official script and seal script. Most of them have worked hard on the traditional post study, and their creations have the characteristics of confusing the two or breaking the post with a monument. Deng and Ruan Yuan demarcated the boundary, and the broken post school with a monument in front of it was called Qianbei School. Since then, Zunbei School has been called Zunbei School. Representative figures are: Zheng Zhi, Cheng Yi, Jin Nong, Zheng Xie, etc.
37. Briefly describe the characteristics of Wumen School of Calligraphy.
A: At the beginning of the Ming Dynasty, Zhu Yuanzhang restrained Suzhou's literati and economy because his opponent Zhang Shicheng had occupied Wu and Suzhou's economy was developed and there were many rich households. When he became an ancestor, the capital moved northward and the political center moved northward. During the Chenghua period, this policy of political and economic bondage was gradually relaxed, and the creation of literati painters became free. In the mid-Ming dynasty, calligraphy gradually walked out of the fog of the early stage of Taige style. Taige calligraphy is for the needs of the exam, while Wu calligraphers are not bound by the court, and their creation appears free. Therefore, calligraphy activities are centered on this, and they have also turned from Beijing, the political and cultural center, to southern Jiangsu, where the commercial economy is prosperous, especially Suzhou, marked by the appearance of Wumen calligraphers. Suzhou, a metropolis in southern Jiangsu, has a long history, developed culture, rich economy and prosperous business. Scholars gathered here, and the geographical concentration of calligraphers was particularly prominent in this period. Wumen Calligraphy School became the largest calligraphy school in the history of Ming Dynasty, which broke the superficial prosperity and emptiness of calligraphy since the early Ming Dynasty and became the mainstream of calligraphy in the middle of Ming Dynasty. These calligraphers can get rid of the shackles of cabinets, abandon those who study and catch up with the Tang and Song Dynasties, and advocate the development of individuality and independence.
38. Briefly describe the important role of Emperor Taizong in the history of calligraphy in the Tang Dynasty.
A: Emperor Taizong was well aware of the principle of ruling the world by culture and formulated various policies suitable for the development of calligraphy. He set up a special educational institution-imperial academy, and took calligraphy as one of his learning contents. He set up a doctor of calligraphy to teach and implemented an important measure of taking books as officials. In the imperial examination, calligraphy is an exclusive subject, and the selection of officials is no exception. Emperor Taizong loved Wang Xizhi's calligraphy and personally wrote a biography for him, which established Wang Xizhi's exclusive position in the early Tang Dynasty and determined the development direction of calligraphy in the early Tang Dynasty. As a result, famous artists came forth in large numbers and the cause of calligraphy flourished.
Six, essay questions (15 points for each small question, a total of 30 points)
39. Try to describe the characteristics of Zhao Mengfu's calligraphy and its profound influence on the history of China's calligraphy.
A: Zhao Mengfu held high the banner of reviving the ancient law, which made the calligraphy of the Yuan Dynasty rejuvenate after more than a hundred years of depression in the Southern Song Dynasty, showing a thriving scene. Zhao Mengfu's view of calligraphy is an excellent return to the study of calligraphy in Jin Dynasty. He opposed learning calligraphy from Yan Zhenqing, pointing out that he traced back to the two kings of the Eastern Jin Dynasty and was completely retro in practice. His contribution lies not only in his calligraphy creation, but also in his calligraphy thought, pointing out that calligraphy should be pen-based, and efforts should be made to form words. It is not easy to use a pen through the ages, which has become a famous assertion in calligraphy theory since the Yuan Dynasty, prompting calligraphy. It was also from the brushwork that he began his retro style. He emphasized that it is beneficial to study calligraphy to ponder over ancient calligraphy posts and know the meaning of using pens. He put forward the viewpoint that brushwork is the first and word formation is the second, which is an important condition for calligraphy to be passed down as a traditional art. It is not only of great significance in the Yuan Dynasty, but also a famous saying guiding calligraphy practice today. Zhao Mengfu's contribution to calligraphy is outstanding. He influenced a large number of people in the Yuan Dynasty and formed a group of Zhao calligraphers with distinctive styles, which made the calligraphy circle in the Yuan Dynasty under Zhao calligraphy style. His calligraphy also influenced the Ming Dynasty, and his calligraphy style influenced for three centuries.
40. What's the difference between Wang Xianzhi's book style and Wang Xizhi's? Please use his representative works to explain the connotation of "beauty in the past but beauty in the present".
Wang Xianzhi's calligraphy is different from Wang Xizhi's. More beautiful than his father, in line with fashion aesthetics. It loves beauty but is thin, and people are affectionate. His cursive calligraphy is passionate and carefree, which can be called the most romantic brushwork. It can be seen that it breaks the shackles of tradition and highlights the feelings of life. His works in small letters, such as "Ode to the Goddess of Luo", turn the inner awe of the king into an external development, and the accumulation into an external release, with strong handwriting and distinctive personal characteristics. Cursive scripts, such as Mid-Autumn Festival posts and farewell posts, are magnificent, appearing up and down, and continuous. The running script Nineteen Posts is flat in shape, mixed with grass, lines and letters, accurate in brushwork, calm and open, forming an unprecedented new book style with full spirit and charm. Wang Xianzhi created cursive script on the basis of his father Wang Xizhi, completed a stage of reform since Zhong You and Wang Xizhi, and made the calligraphy of literati develop to a new height. His calligraphy is the extension and development of Wang Xizhi's calligraphy style. The so-called "father and son are the present, and today's people are the present" includes Wang Xizhi's "harmony with God" and "magic soldiers".
