The Qing Dynasty, a foreign occupation, was rife with drastic social changes. During this era, navigating experiences and coping with contradictions and conflicts became an important literary theme. Fang Yizhi based his Theory of Body and Effect on concepts such as “The change of order at the same time brings about a stillness at the same time,” and “difference is equality” from his family’s studies of I Ching. The Theory of Body and Effect believes that all things, with their bodies and their experiences and the conflicts in experiences, can complement, borrow from, and contrast one another while remaining one and equal. Fang Yizhi uses this theory to reinterpret juxtaposition, metaphor, and exposition. He also added to the poetic concept of “forlornness,” which was invented by his teacher, Juelang Daosheng. Using these innovations, he constructed a poetry-writing theory that reveals the oneness and complementation of extreme opposites. Poems written according to this theory are able to resolve and balance opposites in social and daily themes. Fang Yizhi’s theory of poetry influenced his hometown of Tongcheng. As a result, poems written by the poets of Tong Cheng often address the coexistence of conflicts and opposition and reveal the truth that extreme opposites coexist by borrowing from and contrasting each other. As a result, the poetic themes are expressed in a more well-rounded, conclusive way. The poetry of Tongcheng in the early Qing Dynasty is quite rarely discussed in academia. To add to the academic literature of early-Qing poetry, this essay will conduct a preliminary analysis of these poems based on Fang Yizhi’s theory of poetry-writing, combining the thoughts of I Ching with poetry.
