Bang, bang, bang... He banged the door hard and jumped up anxiously. What's going on? At around 4:50 pm on June 28, at Jinan Wildlife World, three brown bears saw the animal caretaker walking toward the inner cage, and they ran over in unison, wanting to go home.

"At this point every day, It’s when the animals return to their cages. If it’s a little slower, they’ll smash the door and jump high in a hurry,” the animal care worker said.

The brown bear is a mammal bear family animal, also known as grizzly bear, horse bear, human bear. Brown bears are mainly found in Eurasia and most parts of North America. Brown bears are primarily active during the day and are omnivores, and their diets vary depending on their habitat and season.
