You may have heard the term "The Sleeping Giant" being applied to China, but as German photographer Bernd Hagemann found out, the term may actually have a more literal meaning: Chinese people can sleep anywhere, anytime!
Indeed Bernd has documented this phenomenon: Here's a fantastic gallery of sleeping people in China, categorized as "hardsleepers" (those who sleep in pretty hardcore positions), "softsleepers" (who needs a little padding) and "groupsleepers" (those who sleep with friends, literally!)
But about that thing.. how are children supposed to play on it? It's kinda weird IMO :P
I have a friend in China (near Shanghai) that speaks of this– there’s a specific word in Chinese that conveys the concept– they sleep almost ANYWHERE. I think it’s most prevalent at certain times of the year (like the Spring). People have a tendency to feel sleepy. We have 'spring fever' they have 'sleep fever'
