A 'monkey king' atop an ice cap

The Tibetan macaques blast toward the confetti of corn kernels flying from Zheng Yungui's fingertips like an explosion chasing sparks.

The primates screech and lunge to snap up the food. Babies cling to mother's bellies.

The 45-year-old staffer of the Dagu Glacier Scenic Area is better known by his local nickname, "the monkey king", referencing the Journey to the West, known as one of China's "four great novels".
