Yanwu Gu

Gu Yanwu (1613–1682), also known as Gu Tinglin, was a Chinese historian, philologist, poet, and thinker from Kunshan in Jiangsu. Living through the collapse of the Ming dynasty and the rise of the Qing, he became one of the best-known Ming loyalist scholars of his age.

Rather than pursuing official success, he spent much of his later life traveling, reading, and gathering notes. He is especially remembered for advocating rigorous, evidence-based scholarship and for criticizing empty book learning, an approach that helped shape the later tradition of evidential research in Qing intellectual life.

His writing ranges across history, classics, phonology, and geography, and readers still encounter him as a serious but energetic mind: practical, wide-ranging, and deeply concerned with how learning should connect to the real world.
