Mi Fei (1051-about 1 108) in the Northern Song Dynasty, with the character stamp, Xiangyang Mantu and Haiyue Waishi. Originally from Shanxi, he moved to Xiangyang and was called "Mi Xiangyang". Historically speaking, he is eccentric, likes to wear Tang suit, and is neat. He is called "elder brother" when he meets stones, so he worships him, so he is called "Mi Dian". At the age of six, I learned hundreds of poems, studied books at the age of seven, wrote tablets at the age of ten, and entered the officialdom at the age of twenty-one. He is really a precocious eccentric. In calligraphy, he is one of the "four calligraphers of Song Dynasty" (Su, Mi, Huang and Cai), which is second to none. His writing style is bold and unconstrained, and his statutes are rigorous. Su Dongpo praised him as "true, diffuse, official and seal, as calm and happy as a horse"; On the other hand, he also created the method of "Mijia Yunshan" in landscape painting, made good use of "fuzzy" pen and ink to create the misty scenery in the south of the Yangtze River, and reproduced layers of mountains with scattered thick ink, Jiao Mo, horizontal dots and dots, which is called "Midian" in the world. It is admired by many painters in later generations and imitated by others. His son Mi Youren left many works in the world, which enabled this painting style to continue and led to a new level of "literati painting", which was praised by the history of painting. Historians have different emphases on whether Mi Fei values books or paintings.
