The history of Chinese calligraphy is almost the same as the history of China itself. Calligraphy is one of the noble Chinese arts. Regarded as the most abstract and sublime form of art in Chinese culture, "Shu Fa" (calligraphy) is often thought to be the most revealing of one's personality. Chinese calligraphy serves the purpose of conveying thoughts but also shows the abstract beauty of the line. Rhythm, line, and structure are more perfectly embodied in calligraphy than in painting or sculpture.
