There is information about Mimi.

Mi Fei (105 1 year-1107), formerly known as Kun, later renamed Kun, whose real name was Mi or Qian, was a native of Xiangyang, Hubei Province, and was then called Haiyue Waishi, also known as the descendants of Kun Xiong and Huo Zheng.

Calligrapher, painter and painting theorist in Northern Song Dynasty, together with Cai Xiang, Su Shi and Huang Tingjian, are also called "Song Sijia". He used to be a school book lang, a doctor of calligraphy and painting, and a foreign minister of the Ministry of Rites. Originally from Shanxi, he moved to Xiangyang, Hubei, and then settled in Runzhou (now Zhenjiang, Jiangsu).

There are many special strokes in Mi Fei, such as the turning of the right corner of the word "door", the steep rise of the vertical hook, the crab claw hook, etc., all of which are taken from Yan's running script; The shape of the body is cut, when it comes from the imitation of European characters, and it has been kept for a long time; Shen Chuanshi's running script is similar to Chu Suiliang's.

"Unique four sides" and "brush strokes" may come from Mi Fei's Chinese character season exhibition. Chu Suiliang's brushwork is the most varied and vivid, which is in line with Mi Fei's taste. He once praised himself for saying, "If you are familiar with horses, you will follow others, but there will be no arrogance."

Mi Fei has his unique experience in the distribution, structure and use of calligraphy. The requirement is "stable, not strange, not old, not fat", which is probably what Jiang Kui wrote, "Don't hang down, don't shrink."

That is, it is required to achieve unity in change, and to integrate the opposing factors such as wrapping and hiding, fat and thin, sparse and dense, simplicity and complexity, that is, "bones and muscles, meat and fat, and charm are all there, just like a good scholar." In composition, attention is paid to the overall charm, the perfection of details, ingenious conception, changing with the situation in the writing process, and ingenuity.
