The first light-hearted comparison between Xi and Pooh reportedly first surfaced in 2013 when Obama met with the Chinese leader, and netizens compared the former to Pooh's lanky friend Tigger.
Honey-loving resident of the Hundred Acre Wood, Winnie the Pooh, has apparently run afoul of Chinese censors yet again.
Currently, attempts to write "Winnie the Pooh" in China's famous social network Weibo end up with a pop-up warning "illegal content".
