"I'd know which each of them gradings, ef I see em in Chiny" Hannah says this in chapter ten on the first page and I don't know what it means or what it could mean.
That is interesting. I looked for it but couldn't find an answer. The fact that the C is capital leeds me to think it is some kind of city or place. There is a city in Belgium but I'm not sure that's it.
Here's my best guess , I think Hannah was referring that there are many gardens in city Chiny , Belgium and still she would identify each of them as they're unique to each other just like there personality.
