From Zhang Zhongjing's 《金匮要略》 (Han): 夫风之为病，当半身不遂 — "when wind becomes an illness, it causes one-sided non-response of the body." Chinese medicine's classical term for stroke paralysis, now standard modern medical Chinese.
mistakes
The character 遂 here reads suí ("to follow, respond"), not the usual suì. Same character as in 毛遂自荐 (suì) — but here with its rarer reading.
