9th century) was a Chinese Zen monk-poet lived in the Tang dynasty, associated with Hanshan and Shide in the famed "Tiantai Trio" (天台三聖).

Legendarily, Feng appeared one day at Guoqing Temple (located by the East China Sea, in the Tiantai mountain range), a 6-foot-tall (1.8 m) monk with an unshaven head, riding a tiger.

The circumstances of his death are as murky as his life: the stories in which Feng is any more than a name or foil for Hanshan cease after he healed a local prefect.

Shenxiu to demonstrate his mastery of Zen wrote the following poem: The body is the Bodhi Tree \ the mind like a clear mirror.

See for example Feng's second poem, which expresses strictly Buddhist ideas: (The 'Three Worlds' refer to either those of the past, present, and future; or alternatively, those of form, formlessness, and becoming.)
