What is the name of the running script masterpiece by Su Shi written during his exile?

The running-script masterpiece by Su Shi written during exile is The Cold Food Observance.

Also called Han Shi Tie or the Huangzhou Cold Food Festival Poems, The Cold Food Observance is a handscroll combining two poems with expressive running-script calligraphy. Su Shi wrote it in 1082, during his exile in Huangzhou in present-day Hubei, after political conflict and accusations of literary misconduct damaged his official career.

The poems describe unrelenting rain, a poor dwelling, cold food, wet firewood, distance from the imperial court, and separation from ancestral graves. Their bleak imagery is mirrored by the writing: the characters vary in size and energy, and the brushwork becomes increasingly forceful as emotion rises. This fusion of literary meaning and physical movement is a major reason the work is regarded as Su Shi’s finest calligraphic achievement.

The title can cause confusion because English translations vary. “Cold Food Observance,” “Cold Food Festival Poems,” and “Huangzhou Cold Food Poems” refer to the same celebrated work. It is also frequently grouped with Wang Xizhi’s Lanting Xu and Yan Zhenqing’s Draft of a Requiem to My Nephew among China’s great running-script masterpieces.
