Badashanren's calligraphy creation can be divided into five periods: first, the period of biography, mainly studying Ouyang Xun; Second, a mountain period, mainly from Dong Qichang; Third, during the donkey period, I mainly studied Huang Tingjian and Yi Heming. In the early stage of the Fourth and Eighth National Congress, after studying the brushwork of Zhong You, Wang Xizhi and Yan Zhenqing, they formed a unique style, with strange fonts, but the pen was too hard; In the late period of the Fifth and Eighth National Congress, there were two styles in parallel. One was the further development of the painter's calligraphy in the early period of the Eighth National Congress, which became increasingly round and muddy, and the bald pen was carried by hanging the elbow as the center, which did not seek the shape but was extremely simple and vigorous. The other was a small running script, which was close to Wang Chong in the Ming Dynasty, hiding his head and protecting his tail, and his style was quite quiet. The works in the biography period can be found in the preface and postscript of the book Biography from Sketch. Fiona Fang has both a pen and a pen, and his strength is steep and dangerous, and his statutes are strict, which obviously won Ouyang Xun's method. Calligraphy in this mountain period, as a representative of the opening title of Plum Blossom Map, has five unique running scripts, and its branches are white, sparse and light, and Mo Yun's brushwork is round and beautiful, which is full of fragrance and charm.
The works in the donkey period, such as Ode to Liu Ling's Wine and Morality, consist of 57 lines, ranging from 2 words to 5 words in each line, with various sizes. The middle palace is tightened, the four feet are relaxed, and there is a heroic spirit; With a pen, you are happy and calm.
In the early period of the Eighth National Congress of the Communist Party of China, the style of writing with a pen still followed the style of donkey period, but it began to turn to strange style, which is clearly visible in Lu Hongshi.
The works in the later period of the Eighth National Congress, such as the axis of Four Proverbs of Cheng Yi, the axis of Inscription and Postscript of Flowers on the River, and the axis of the Book of Lay Scholars in Zeluan Dongpo, follow the previous book style and become more boundless, round, plain and old-fashioned. The brush stroke is purely based on the meaning of seal script, and there is no trace of its beginning and end. The strokes are rare, round and concise. Although it is cursive, the pen can be broken, and the lead is rarely used, and there is no trace, which makes it particularly indifferent and ancient. Pen and ink to sink muddy feelings, into Zen and Taoism, bitter and cold, and get rid of the dust and customs. "The Heart Sutra in Lower Case" is just "gorgeous, returning to plain", and it has no strange power in the early stage of the Eighth National Congress, but adopts the ancient style of Jin and Tang Dynasties directly, reflecting his peaceful and detached mood in his later years.
