The stylization of the opening pen makes calligraphy simple and mechanical, not the expression of free spirit, so it is "simple". From the perspective of realm meteorology, Qigong's calligraphy did not reach the level of ancient calligraphers. Although some of his calligraphy was respected by some people, the realm connotation of China's calligraphy was far more than that. Qigong's calligraphy is neat and beautiful, but the brushwork is not "ancient", and it is more interesting and less interesting. The pen is limited to monotonous "flow", "beauty", "beauty" and "smoothness", but I don't know the importance of using a pen in calligraphy, so the beauty of calligraphy is less than the quality of calligraphy. Qigong's calligraphy is connected by "doing", and the axis of the characters is straight and continuous, which is similar to the operator. His composition also has a fatal weakness, which is difficult for ordinary people to perceive. Wang Xizhi said, "If it is straight and similar, it looks like an operator, the top and bottom are whole, and the front and back are flush, it is not a book, but it is worth mentioning." Because he is writing, rather than treating calligraphy art as an expression of free spiritual feelings. Chen Zhenlian pointed out that "real calligraphy" is an art that absolutely emphasizes the subject spirit, including the author's lyricism and expression, and incorporating individual aesthetic ideas into the form. Its basic point is aesthetics rather than practicality; Its form of expression is the establishment of a concise and abstract form containing rich contents such as emotion, meaning, environment and interest, rather than a practical and instrumental pattern of general beauty such as neatness, uniformity and uniformity. " From this point of view, Qigong calligraphy is more practical than artistic.
