Chinese calligraphy style in Song dynasty was described as sentimental later by art critics. Mi Fu was a leading figure of the trend. His writing is characterized by both the oblique characters and the agitated and changeful brushstroke. Containing his eight poems of total 657 characters, this hand-scroll was named by its support - the silk of Sichuan Province. What made the silk particular was that it tended to produce drier strokes than that on rice paper and only a few Chinese calligraphy artists in the past ventured to use it.
