The yeren (Chinese: 野人, 'wild man') is a cryptid apeman reported to inhabit remote, mountainous regions of China, most famously in the Shennongjia Forestry District in the Hubei Province. Sightings of "hairy men" have remained constant since the Warring States Period circa 340 BCE through the Tang dynasty (618–907 CE), before solidifying into the modern legend of the yeren. Generally, they are described as savage, strong, and fast-moving, living in mountain caves and descending only to raid villages in search of food or women.
Scientific interest in such apemen erupted in the 1950s and 1960s in conjunction with pseudoscientific discoveries relating to Bigfoot and the yeti, but pressure by the Maoist government to leave behind these kinds of legends and folk stories repressed further interest in the yeren until its dissolution in 1976. Afterwards, large expeditions were launched by the Chinese Academy of Sciences to investigate alleged eyewitness accounts, footprints, hairs, and bodies as "yeren fever" took hold, with scientists working with an unprecedented reliance on citizen science. The yeren was often speculated to be a far removed human relative, such as Gigantopithecus or Paranthropus robustus. All forwarded evidence of the creature originated from known animals — namely bears, monkeys, and gibbons — and scientific interest waned by the late 1980s. Nonetheless, organized yeren research still persists, though no serious scientific institutions recognize such apemen.
The creature has become an artistic icon of wildness and nature, and was used in the wake of the Cultural Revolution to challenge sexually restrictive and egalitarian ideals, as well as to address deforestation and other environmental issues in China.
