Because of a well-spreaded lie about Chairman Xi banning Winnie the Pooh in China over memes comparing him to Winnie. And thus started an endless supply of Chairman Xi being molded with the Pooh Bear. It honestly just feels like a racist caricature at this point.
As far as I know it literally is a racist caricature. The guys who originally said Winnie the Pooh looks like Xi because Winnie the Pooh is yellow.
That's definitely it. They're literally teaching kids about China while they're completely illiterate about China.
