They are doing damnatio memoriae on a footballer (who plays for Real Madrid), canceling his branded products, no longer mentioning him in news stories, and saying he should stay out of China, because he indirectly implied that Mao was a dictator.

So, OK, that's a kind of social harmony: they're very unified in telling you what you mustn't even suggest.
