I think the overuse of the term "civilized" stands out a lot here, and to be honest it sounds incredibly patronizing. It seems people are reminded against such behavior in the West, though the word "civilized" isn't used.

China is probably the only country that thinks good behaviour comes from slogans (e.g. that making children memorise Marxist quotations will somehow reflect in their behaviour).

Instead of giving people human dignity, a sense of self-worth, and the ability to improve their conditions, the Communist Party would prefer to throw a few slogans out there and imagine that's as good as actual change.

"Learn from Lei Feng, peasants. Now f*ck off, because we've got banquets to attend."

You really ought to go find out more about the world around you. Have you heard the latest riots that's been going on lately? Yes, and in many other places too! 

New Zealand men have to be reminded to be civilised, especially when there are sheep around...

In Dubai there are also signs with "No spitting" in all the metro stations.

also Italy should remind their citizen to act civilized

I see signs in hotels all around the world telling people not to squat on the rim of the toilet bowl.

The problem is really Chinglish.  The Chinese would be civilised if they could understand the signs like we do because we are native speakers.

Here's a few examples:

Chinese people are the politest people!
