"Mi Fu's Nine Foot Slips" is housed in the National Palace Museum in Taipei. There is a volume containing precious ink writings of nine pieces of ruler slips by Mi Fu, the great calligrapher of the Song Dynasty. According to expert research, these nine pieces of ruler-slip writing were written by calligraphers after the age of fifty from the first year of Chongning to the fifth year of Chongning, Emperor Huizong of the Song Dynasty. Some experts commented that these nine pieces of calligraphy, in terms of calligraphy style, are long and short, fat and thin, vertical and horizontal, showing the calligrapher's later mature, self-sufficient, plain and natural style.
