Chiang Wei-shui (Chinese: 蔣渭水; Pe̍h-ōe-jī: Chiúⁿ Ūi-súi; 6 August 1890 – 5 August 1931) was a Taiwanese physician and activist. He was a founding member of the Taiwanese Cultural Association and the Taiwanese People's Party. He is seen as one of the most important figures in Taiwan's resistance movement against Japanese rule. He once wrote a short essay on Taiwan called Certificate of Bedside Diagnosis or Certificate of Clinical Diagnosis (臨床講義) about how the patient (Taiwan) suffered from severe culture malnutrition. Written in the form of a medical examination, it is his most famous work.
