Zhao Mengfu (1254-1322) was the most famous calligrapher and painter in the Yuan Dynasty. He was highly accomplished in the field of calligraphy and painting and enjoyed a high reputation. Zhao Mengfu believed that there are two things to learn about calligraphy, one is the brushwork, and the other is the shape of the characters. The writing technique is exquisite, although it is good, it is still evil; the shape of the characters is wonderful, although it is familiar, it is still fresh. Zhao's calligraphy has an important role that cannot be ignored and has far-reaching influence in the history of Chinese calligraphy.
His representative work "Luo Shen Fu" in small regular script was written in the sixth year of Yanyou (1319). The work's vigorous, elegant and beautiful style is fully mature, the lines are strong and powerful, and it is generous and generous. It can also be regarded as a good model for copying and learning pen calligraphy.
