I was in Shenzhen 2007-2008 and definitely experienced what he did at the beginning of his stay, which it looks to me is Shenzhen in a few parts, though 3 million inhabitants sounds a little off. It's well over 10 million and the big joke there was how ridiculous that is because people say it's double that. Anyway, I never experienced the more negative things he did but things have definitely changed. Some people I know who have stayed never stop talking about the police state feel at sudden moments and how many things are a facade. Places that look incredible look old fast and everything has the feel of prefabrication with no regard for being sustained-they just want it to look good when it's finished. This guy's take on things is pretty interesting because he has a good amount of time to digest everything. He is so set up knowing the language, though his ability to relay information to people there makes him a target for the police. I wonder if they like him using a VPN connection to bypass the website blocking?
His wife's take is also interesting-skip to 1:27 to avoid his VPN plug:
