Internet speeds - It is what it is in China. I've accepted it, doesn't mean that I don't get irked when google goes on the blink just as I'm trying to look up and work out some information. Frankly it's more than just being able to Facebook or Twitter, major blogging platforms such as Wordpress and Blogger are also blocked. And websites that aren't blocked but have social media widgets installed take a long time to load.
I have VPN, both corporate and commercial - it helps a lot, but I'd much rather not have to put up with this.
Oh, and not to mention how chinese online transactions require MSIE. I never use IE, my home computing platforms are Mac OS. So whenever I need to do internet banking or transact on Alipay, I have to boot up the work computer to get it done!
