From 1862 to 1874, the French missionary David sent plant specimens back to France and introduced many new plant species to France and Europe. In addition, 58 new species of birds, 100 new species of insects and many important new species of mammals were discovered in China, including the giant panda, golden monkey and elk endemic to China.
After David came to China for the second time in 1867, he heard that there are many kinds of animals in western Sichuan, and some of them are rare and unknown, so he came to Baoxing County, Ya 'an City, Sichuan Province from Shanghai and served as the fourth generation pastor in Dunchigou Church in Donghe, Mu Ping. 1On May 4th, 869, the hunter caught six "long-tailed monkeys" for David. After careful consideration, David named the "long-tailed monkey" as "upturned nose monkey".
Golden monkeys inhabit areas with relatively high altitude all the year round;
Golden monkey is a typical forest arboreal animal, which lives in the forest at an altitude of 1500~3300 meters all the year round. Their vegetation types and vertical distribution zones belong to four vegetation types: subtropical mountain evergreen, deciduous broad-leaved mixed forest, subtropical deciduous broad-leaved forest, evergreen coniferous forest and secondary coniferous mixed forest. With the change of seasons, they don't migrate horizontally, but only move vertically in their habitats.
In social life, all major clusters take small family clusters as their activity units. Each small family group consists of a strong adult male monkey, 3~5 female monkeys, young monkeys under 3 years old and nursing young monkeys.
