From the perspective of visual perception, Ge Shouzhi of the Qing Dynasty mentioned in "Hanxi Calligraphy Comprehensive Notes? Volume 4 of Yunbi": "The swallowtail is also the official method." However, Ma Yongan made a new use of the "swallow" style, focusing on the swallow-tail style to carefully copy it, thus surpassing the ancients and forming a new set of swallow-tail styles. Therefore, Ma Yongan's calligraphy art not only imitates and draws on the dynamic beauty of the light and swaying willow leaves and bamboo leaves, but also takes the swallow-tail trend to form a swallow-tail body with new structure, new strokes, and new shapes. It is indeed an innovative move in the history of Chinese calligraphy. Its calligraphy style is calm and elegant, with powerful strokes, smooth movements, and more luck. It not only shows the beauty of the calligrapher's temperament, but also maintains the law, high interest and pure lines. The overall beauty of the art of "Horse Calligraphy" is to "horizontally" raise your head to take the momentum, and use the swallow's tail to close the front, showing its beauty and strength, just like a bird entering the forest, as powerful as a frightening dragon, floating like floating clouds, and heartily. As Ma Yongan said in his book: "Painting and calligraphy are within calligraphy and painting, and painting and calligraphy are within calligraphy and painting." The words are like paintings and the paintings are like books, which gives a lively and elegant feeling of "the integration of calligraphy and painting". This creative method and aesthetic interest are exactly the "calligraphy composition theory" that Ma Yong'an has been advocating for many years. It requires calligraphers to have comprehensive theoretical knowledge, artistic accomplishment, creative experience and acquired sensitivity to art categories, etc., and through hard study and study, combined with the current public aesthetic characteristics and social values, so as to write several calligraphers. The fusion of two calligraphy art styles shows a new form of beauty and artistic connotation. In this way, the calligrapher's knowledge, taste, ability, style and artistic level will be expressed through calligraphy works without any disguise. This is an important channel for calligraphers to express their emotions.
