In the third year of Yuanfu (1100), Su Shi was ordered to move to Lianzhou (now Hepu, Guangxi). When passing through Chengmai (now Chengmai, Hainan), he did not meet Zhao Mengde, so he left this note. It is representative of his calligraphy in his later years, as Dongpo once said: "Come out with new ideas and don't follow the ancients." The whole work is written in a letter, and it is natural. The writing of this letter is sharp and the structure is slanted to the upper right. People at the time thought it was quite like Li Yong (Beihai). As Huang Tingjian said: "It is calm and cheerful, just like Li Beihai."
"My book There is nothing you can do with your own ideas, but you have to rely on your own hands to make dots and paintings." This is Su Shi's comment on his calligraphy. The different and traditional brushwork and special knots are the most appreciated parts of his calligraphy.
This work, also known as "Du Hai Tie", is a typical Su Shi style, vigorous, powerful, calm and joyful, and is a representative work in his later years. It is numbered with the character number 801 of Xiang Yuanbian's Thousand-Character Classic "Gu".
