Right, so if it weren't for the Master Gardens, the Xi'an Horticultural Expo 2011 would have been a complete bust. There was a special magazine that was released prior to the Expo detailing all of the projects and which acted as our guidebook. I do not have access to this guidebook but I can ask for the specifics and will post a link or otherwise an update when I do have this information. In the meantime, I've taken the time to transcribe each of the garden's sign posts. In the image above, most of the Master Gardens are located there, with the illustrations corresponding to roughly the real thing. You'll see once you see the photos. There were also the "Student Gardens", just west of the main axis but we'll get to them last, as that's how we traveled the expo site.
