Lin Bu (967-1026), courtesy name Junfu, was a native of Qiantang (now Hangzhou, Zhejiang). He lived in seclusion in the lonely mountains of West Lake, never married, loved planting plums and raising cranes, and called himself "Plum Wife and Crane Son". He was later posthumously named Mr. Hejing by Renzong. Among the calligraphers of the early Song Dynasty, Li Jianzhong, Wang Zhu, and Li Zonge all adopted the style of the Tang Dynasty, and their calligraphy was famous for its plumpness. However, Lin Bu's personality was aloof and unconventional, and his calligraphy was not out of date, but had the purity of a crane. And the plum blossoms are sparse and bright. Su Shi said that his calligraphy is "like the calligraphy of Xitai Shaorou". Shen Zhou of the Ming Dynasty once commented in a poem: "My love for Weng's calligraphy is so thin and hard that the plump clouds wash all over the West Lake. Xitai Shaorou is a true comment, and several lines are clear and translucent with ice." Jade. It seems that the wind is overflowing, and this word and this man are extremely vulgar." Lin Bu's handwriting is included in "Zi Shu Miscellaneous Poems". Although Ni Zan's calligraphy in the Yuan Dynasty is different from Lin Bu's calligraphy in form, it is similar in style and mood to Lin Bu's calligraphy.
