On October 5th at 1:45 in the morning I got on a Cathay Pacific flight to Hong Kong. 

If you recall, I'm participating in an Advisory Group for the United Nations. On this trip I also had a chance to deliver the Crash Course to an audience in Shenzhen. So we can now say The Crash Course has been heard on the Chinese mainland! 

It was one thing for me to read about China’s explosive growth and quite another to go there and see it and feel it for myself. It's real, and its scale is massive.
