For people that don't know much about China (and don't want to bother reading books, etc.), here's an animated video that gives a very good short summary. In just 10 minutes, the video manages to cover Chinese history, language, economy, food, traditions and culture. It even manages to mention some of the modern problems China is facing including the many contradictions, corruption, and the little emperor syndrome (resulting from China's one-child policy).
I'm not sure who created this video, but it seems the script may have been largely copied from an excellent blog called Randomwire written by a Brit living in Hong Kong. In a way, its ironically appropriate that in a video summarizing China, the script is copied from someone else's work. Copying without permission and attribution has a long history in China and, despite laws against it, continues to be prevalent in modern China. However, without the video on YouTube, I might not have come across the randomwire blog (especially the series of articles on China) which I recommend readers also take a look at.
