Chinese scholar and poet who helped revive the ci song form during the early Qing dynasty (1644–1911/12).

Although Zhu's family had been prominent under the Ming dynasty, the collapse of that dynasty in 1644 forced him to spend much of his life as a private tutor and personal secretary to various local officials and men of letters. His considerable intellectual accomplishments, however, won him a summons to a special Qing examination in 1678 and eventually an appointment to the prestigious Hanlin Academy at the court in Beijing, where he became an editor on the official Ming history project. While at the capital he wrote a number of other histories, including a noted history of Beijing and its environs (Rixia jiuwen, 1688; “Legends and Places of Beijing”), and produced his Jingyikao (1701; expanded ed. 1755; “General Bibliography of the Classics”), a massive descriptive catalog of both lost and extant works in the Confucian canon.

Zhu was also a prolific poet, regarded as one of the greatest of the early Qing. He is best known for his role in the revival of ci poetry, a lyric form that had flourished during the Song dynasty (960–1279) and then had fallen out of fashion. He edited a definitive anthology of ci and urged a return to the refined elegance of the form; his efforts influenced a new generation of poets. His own ci were traditional in their emphasis on tonal rules, though somewhat obscure and allegorical in approach.
