Zhao Mengfu, a calligrapher in Yuan Dynasty, is one of the top ten calligraphy posts handed down from ancient times in China. On the whole, calligraphy in Yuan Dynasty is an era of retro innovation. On the basis of the regular script method in the Tang Dynasty, all factions in the Yuan Dynasty tried their best to scale up the second Jin Dynasty and form a generation of ethos. After Yuan Shizu Kublai Khan unified China, he tried to restore the old system by making friends with talented Han Chinese and exploring talents from various aspects. Although he was more open in culture and thought, he strictly restricted the Han people in military and political affairs, financial power, and talent selection in imperial examinations. People of insight could not seek utility in their official career, but still turned to literature and art. Zhao Mengfu was one of the most outstanding representatives in the field of calligraphy.
