On the morning of October 12, Mr. Qin, a forest ranger at the Jiangbin Park Management Office of Liuzhou City, saw nearly 10 monkeys foraging in food while patrolling the mountain in Jishan. He immediately took a cell phone to take a picture of the movements of three monkeys nearby. One of them found that he had food in his hands and came over to "ask for food". This is not the first time a forest ranger has seen a monkey on the stone mountain in Liuzhou. They also saw it in Jishan six or seven years ago.

At that time, Qin saw a little monkey about 40 cm long napping on the treetops and approached gently. The little monkey was very alert and opened his eyes. In order to get close to the monkey, Qin threw the corn and peanuts he carried with him. The monkey flexibly caught it with his upper limbs and placed it beside his nose. After sniffing it, he started to eat it. He also came to him boldly and took the food from his hands. It was very adorable.

After contacting the zoo, Qin learned that these monkeys were crab-eating macaque , also known as long-tail macaque , with an adult body length of about 40-47 cm and a tail length of 50-60 cm. The coat color ranges from gray-brown to reddish-brown, and the fur on the abdominal hair and the medial side of the limbs are light white; the crest hair is covered with brown-gray surface, with whisker hair, naked eyes, and white triangle area on the upper side of the eyelids; the ears are upright and the eyes are black. The nose is flat and the nostrils are very narrow. He likes to feed crabs and shellfish on the beach, so he is called crab-eating macaques, and is a national second-level key protected animal.
Nearly 10 crab-eating macaques appeared in Shishan, Liuzhou, probably came out of nearby breeders in their early years. Its gene is similar to that of humans, and it is also a medical experimental animal. It is often kept as a pet.

Crab-eating macaques live in tropical rainforests, primeval forests, secondary forests, and woods near rivers. They also like to live in freshwater swamps, shrub grasslands, and lowland primeval forests. Crab-eating macaques like to eat crabs and like to live in forest irrigation areas near the water source; especially those vast areas with rugged rocks, cliffs and streams mixed with streams, rivers, valleys, and green trees, are their most ideal places to live. I like to live in groups, often in groups of dozens or hundreds, led by the Monkey King, living in groups in the mountains and forests. I like to climb vines and trees, and I like to search for cliffs and caves.
