In the artistic community, music and dance are inseparable. In ancient China, the word "music" often included "dance", so it was called "music and dance". In the West, the famous dancer Duncan also believes that dance is the "visual incarnation of music." So in China, calligraphy and dance also contain an aesthetic relationship that is correspondingly integrated and similar. Zhang Xu, a great calligrapher of the Tang Dynasty, learned about calligraphy after seeing Lady Gongsun dancing with her sword. Calligrapher Huai Su's cursive script is "round and can be turned, and the words are well-joined, just like the dance of "Sanglin"." This metaphor of calligraphy and dance can reveal the historical relationship between calligraphy and dance. Mr. Zong Baihua once said: Dance is a typical example of all artistic realms in China. Chinese painting and calligraphy tend to fly. Calligraphy implements the spirit of dance, and dance movements show the ethereal space. Calligraphy can be inspired by dance, and dance can also be understood by calligraphy.
