Haiyue mingyan 海嶽名言 "Famous words about sea and mountains" is a critical book on calligraphy. The 25 brief chapters or rather statements were compiled by disciples of the famous artist Mi Fu 米芾 (1051-1107) according to his oral instructions.
It can be said that Mi Fu admired the natural elegance of ancient paintings from the Wei 曹魏 (220-265) and Jin 晉 (265-420) periods, while he apparently had only disrespective words for many of the famous masters of the Tang 唐 (618-907) and the early Song period 宋 (960-1279). He directly says that Cai Jing 蔡京 (1047-1126) "could not master the brush" (bu de bi 不得筆), that Cai Bian 蔡卞 (1048-1117) "mastered it but missed rhythm" (de bi er fa yi yun 得筆而乏逸韻), that Cai Xiang 蔡襄 (1012-1067) "exerted force on the characters" (le zi 勒字), that Shen Liao 沈遼 (1032-1085) "stringed them up" (pai zi 排字), Huang Tingjian 黃庭堅 (1045-1105) "sketched characters" (miao zi 描字), and Su Shi 蘇軾 (1037-1101) merely "painted them" (hua zi 畫字). This leaves quite an image of arrogance displayed by Mi, even if he admitted that Ouyang Xun 歐陽詢 (557-641), Yu Shinan 虞世南 (558–638), Cai Xiang or Huang Tingjian had immense skills in their use of using the brush and opened new ways of painting by disclosing unprecedented subtlety in their artworks.
Some phrases give an insight into Mi Fu's own concepts of calligraphy, namely that "big" (complex) characters should be like "smaller" (simple) ones, and vice versa, and that big characters should provide the smaller ones with the power of brushstrokes in order to receive a balanced picture (bi shi bei quan 筆勢備全), while smaller characters could contribute strength, framework and spirit (jingu shenqi 筋骨神氣). This would create an overall picture of stability, without improper protrusions, meagerness, or luxuriance.
