Someone or something happened to this blog. It either was hacked or suffered from a corrupted highly corrupted WordPress auto-update. Either way, the whole site has been deleted by something or someone other than me. No backups have been archived by either Worpress or my hosting provider. Please be patient as I manually reupload years of content. Think of RealChangzhou as temporarily out of / missing in action. To anybody who has found value in this blog, rest assured. Much of it will be coming back. It’s just going to take some time and effort. And, most of all, thank you very much for reading over the years.
