Cold food post. This post is a representative work of Su Shi's running script. This is a poem of joy and excitement, which is the sigh of life written by Su Shi on the Cold Food Festival in the third year after he was demoted to Huangzhou. The poem is desolate and sentimental, expressing Su Shi's melancholy and loneliness at this time. The calligraphy of this poem was inspired by this mood and situation. The calligraphy throughout the text is full of ups and downs, radiant and unrestrained, without any rash strokes. "Han Shi Shi Tie" has a great influence on the history of calligraphy. It is known as "the third running script in the world" and is also the best among Su Shi's calligraphy works. As Huang Tingjian wrote after this poem: "This book combines the writing styles of Yan Lugong, Yang Shaoshi, and Li Xitai. I tried to make Dongpo recreate it, but it may not be as good as this.
