What are the characteristics of calligrapher Sha Menghai's calligraphy?

Calligrapher Sha Menghai's calligraphy is characterized by "strength" and "nationality". He turned from pursuing "Shang Yun" to pursuing "respecting stone" of Beibei School, and from regular script creation to cursive script creation. He lived in the Han and Wei Dynasties and studied in the Song and Ming Dynasties. He worked hard in Zhong You, Wang Xizhi, Ou Yangxun, Yan Zhenqing, Su Shi, Huang Tingjian, Huang Daozhou, Zhang Ruitu and others in the Qing Dynasty, and finally formed his own unique calligraphy style. It is this inheritance and extensive absorption of excellent calligraphy tradition that makes Sha Menghai's calligraphy have more China cultural connotation and weight, and more national characteristics. Behind his dignified and vigorous calligraphy, he typically embodies the deep, broad and simple national character. The more national it is, the more cosmopolitan it is. "Sha Ti" calligraphy is not only the creation of individuality, but also the creation of nationality and world. Now Sha Menghai's calligraphy is listed as a national treasure by the state, and it is forbidden to flow out, which is a good proof.
