From a Ming-dynasty couplet written by the official Yang Jisheng (
杨继盛) before his execution for impeaching the corrupt minister Yan Song:
铁肩担道义,
辣手著文章 — 'Iron shoulders bear moral duty; a pungent hand wields the pen.' Li Dazhao (
李大钊), co-founder of the Chinese Communist Party, famously rewrote it as
铁肩担道义,
妙手著文章 and used it as his credo; this is the version most quoted today.
