Su Shi (1037-110/year) was born in Meishan, Sichuan. The famous writers, painters and calligraphers in the Northern Song Dynasty are the people with the highest literary achievements in the Song Dynasty. His poems are bold and unconstrained, and his prose achievements are one of the eight masters in Tang and Song Dynasties. He, his father Su Xun and his brother Su Zhe are famous for their poems, and they are also called "Three Sows". Su Shi not only made outstanding achievements in literature, but also was a famous painter and calligrapher in the Northern Song Dynasty. His calligraphy tries to break through the rules of the ancients, advocates not sticking to the rules, creates new forms, and attaches importance to the expression of personal thoughts and feelings in his works. Su Shi once said, "I won't do this book with my heart." Among Su Shi's main calligraphy works handed down from generation to generation, such as Huangzhou Cold Food Sticker, Dongting Spring Scene, Zhongshan Songlaojuan, Qianchibi Fu, Ashoka Temple Chen Kuige Monument, etc. It can be seen that Su Shi's calligraphy strives to be vivid with his pen, pays attention to expressing his personal style and opposes binding the calligrapher's thoughts with traditional laws. Su Shi is a leading figure in the style of "respecting meaning". He leads the new generation with the spirit of "although he is not good at writing, he is not as good as literary talent", especially the Cold Food Post written when he relegated Huangzhou, which is even more praised as the third running book in the world.
Huang Tingjian (1045- 1 105), whose real name is Lu Zhi, later called Huanggu, later named Fu Weng, was born in Fenning, Hongzhou (now Xiushui, Jiangxi).

Later, because of his outstanding poetry and calligraphy, he shared the same interests with Su Dongpo and was called "Su Huang". His poetry was the first of its kind in a generation, and later generations called it Jiangxi Poetry School. In calligraphy, the teacher also advocates giving full play to personality, thinking that "it is realistic to become a family when you follow other people's plans." "Huang Tingjian's calligraphy wins with exaggerated and peculiar brushwork charm. In his words, the palace is tightly set, and the long strokes are spread around exaggeratedly, forming a strong contrast between density and density, which makes it interesting. Huang Tingjian's cursive script is proud of Zhang Xu and Huai Su, and his achievements are the most outstanding. His pen is thin, vigorous, beautiful, fantastic, with various shapes, and a little bit of seal script is integrated into it. Chao once called him "Cao Zhang is like Jin people, and Canon Cao is like Tang people". The most representative work is Zhu Shangtie, which has strong lyricism, extraordinary writing style, extraordinary brushwork, strange lines, ups and downs and colorful. In addition, his cursive masterpieces include Li Bai's Memories of Time Past and Liu Mengde's Poems of Zhi Zhu.

Mi Fei (1051-107), with a seal, was born in Taiyuan, Shanxi Province, and later settled in Zhenjiang, Jiangsu Province. Because of his eccentric personality and crazy behavior, he was called "Senior Brother" when he met a stone, so he was called "Mi Dian". As a doctor of painting and calligraphy, Song Huizong was called "Minnan Palace". Mi Fei is good at poetry and prose, painting and calligraphy, and appraisal. He is a painter, appraiser and collector. In painting, Mi Fei is good at ink and wash landscapes, and together with his son, he created Mi's Yunshan. Unfortunately, his paintings do not exist in the world. Mi Fei's calligraphy style is unrestrained and his statutes are rigorous. His calligraphy style is the most comprehensive in Song Sijia, and his brushwork is also the most diverse. Because he is good at learning from others, he is called "Ji Gu Zi". Mi Fei worked hard on calligraphy all his life, and his greatest achievement was running script. Most of the famous posts since the Southern Song Dynasty are engraved with his calligraphy, which is widely spread and has far-reaching influence. Among the "Four Great Calligraphers of Northern Song Dynasty", he is second to none.

Cai Xiang (10 12- 1067), whose real name is Mo Jun, is a native of Xianyou, Fujian, a Tiansheng Jinshi, a bachelor of Duanming Temple, and a calligrapher in the early Northern Song Dynasty. Cai Xiang's integrity was praised at that time, and his calligraphy was also wonderful. Su Dongpo praised him "I am the first". Early calligraphy benefited from Yu Shinan in the early Tang Dynasty. In his later years, he can learn from Yan Zhenqing, convey the charm of the face and body, and emphasize the ancient meaning and statutes. His block letters are dignified and steady, his running script is simple and elegant, and his cursive script adopts the method of flying white, which is called "scattered grass", and it is self-contained and very particular. There are not many works handed down from generation to generation by Cai Xiang, mainly including Wan 'an Bridge, Zhou Jintang, Xie Ci's Poems on Imperial Writing, Holding Book Sticks, Tea Notes, Poems Written by oneself and so on. Among them, Tea Story is his favorite lower case in his life, and it can be said that it is the best work in his lower case. The font is vigorous and powerful, and it abides by the statutes. However, he is informal, lively and calm.
