if anyone actually read the articles, the reason is that China's President (President Xi) was being mocked by people. These people were using Winnie the Pooh as a representative of him, and other characters as other world leaders.
Honestly, this kind of behavior is unacceptable. People shouldn't be attacking any world leader like that.
Just like that moron Kathy Griffin who posted a picture of her holding a (fake) severed head of the United States President Donald Trump. She got what was coming to her. For hell's sake, he is a world leader. No matter how much you don't agree with him or don't like him, you just don't do that. It's common sense, and now those idiots who mocked President Xi have taken away one of the greatest cartoons from China.
