Sun Deng
Sun Deng 孫登 (f. 230–260 CE) was a Daoist sage-recluse, a zitherist, and allegedly the last master of transcendental whistling. Chinese literature has various anecdotes about Sun Deng refusing to teach the musicians Ji Kang (223–262) and Ruan Ji (210–263), two of the iconoclastic Seven Worthies of the Bamboo Grove.
