A zoo in Hong Kong, China is accused of placing a human in a bear suit. Because of a video where the sun bear stands and how it interacts with the sightseers.

Angela's (the bear) humanistic characteristics, such as standing, have led people to think it was a costume. People are also saying that Angela's rear end is "too baggy" and resembles a costume.

Though bears may not be seen often standing up, they actually do. They stand up to see in front of them, and since the bear can smell the people but can't see it that is the reason for him standing up. 

The zoo's official Twitter made a tweet from the perspective of the bear saying "Some people think I stand like a human, and it seems that you don’t understand me that much,"

Also, a researcher researching sun bears for years confirms that Angela is 100% a sun bear, and states"Sunbear very human-like". A visitor from the zoo who saw Angela said "Never once did I think it was a bear in a costume."
