The sinology connotation of calligraphy culture is Confucian calligraphy art. As a social ideology, it is a reflection of social life, and it must also contain objective social life and the calligrapher's own thoughts and feelings. Confucianism has influenced our society for more than two thousand years. Calligraphers, especially those in the old days, are not descendants of Confucianism who read a lot of poetry books. Can the creation, appreciation and criticism of calligraphy not be influenced by Confucianism? Calligraphy requires a balanced, fair, dignified and beautiful structure. Confucianism advocates that neutrality is beauty, righteousness is the center, and form expresses meaning. In calligraphy, strokes should be interspersed and avoided, and each department should echo and coordinate. Confucianism requires that "harmony is the most precious, and the doctrine of the mean is harmony", and benevolence, righteousness and propriety are the principles of being a man. In calligraphy creation, it is necessary to emphasize individuality without losing individuality, while Confucianism requires "a gentleman is harmonious but different, neutral but not flowing." Calligraphy and painting have the same origin since ancient times. Books are drawn for the mind. When creating, we should learn from nature, describe the beauty of calligraphy and evaluate the level of calligraphy. We often use some phenomena or States in nature as metaphors, such as thunder and falling rocks, flying beasts in fear, like cliffs at the beginning of the month, among the stars, and so on. All of them have achieved the unity and blending of man and nature, which is completely consistent with the Confucian concept of harmony between man and nature. Honesty is one of the important contents of Confucianism. In calligraphy creation, honesty is necessary. First, the writing of characters must be standardized, especially cursive. Norm is the concrete embodiment of honesty. If someone doesn't follow the prescribed font structure, who will recognize it? Then, calligraphy works should be inscribed and stamped, not only for the needs of composition layout and color contrast effect, but also to express the author's sense of responsibility and integrity. Signature and seal have legal effect. In calligraphy works, although it is not so serious, the author's expression of sincerity is nothing more serious. Confucianism pays equal attention to both ability and morality, paying special attention to a person's talent and virtue, as well as the requirements for virtue. It is believed that morality is the foundation of talents and pays attention to the unity of internal quality and external performance of personality. Put forward "gentleness is a gentleman". Calligraphers of all ages have followed the principle of "learning calligraphy, learning to be a man first". Calligraphy critics are more critical of people and books. Once a calligrapher is considered to have moral problems, he no longer agrees with his achievements in calligraphy. Cai Jing and Zhao Mengfu, for example, had this different experience. Calligraphers often warn students that it is fundamental to learn to be a man first and then to learn books. Don't you know that this should be Confucianism at all? The Confucian moral norms with benevolence as the core and the moral proposition of paying equal attention to both ability and political integrity have always profoundly influenced calligraphers of all ages to become brilliant and become models for later generations, and Yan Zhenqing is a typical master. Because we don't know much about Confucianism, we can't give more powerful examples, but the internal relationship between calligraphy and Confucianism is very obvious without analysis. In the long-term historical development, calligraphy has always been based on Confucian humanistic morality, and has gradually improved and reached its peak. The creation and evolution of fonts and the formation of calligraphy all contain the essence of Confucianism. From the shape of characters, the essence and charm of calligraphy advocated in different times, we can feel the Confucian style, especially the inscriptions in the Han Dynasty, which are particularly prominent and obvious.
