Unidentified Species

One day my friend sent me a picture from small local pet shop.
Asking which species this is, I was confused, maybe map turtle.
What do you expect from a pet shop in the neighborhood.
This is a suburban store down south from Seoul.
Usually rare would be come across in Seoul's big pet streets. I sent the picture to a fellow well-known-in-cafe mania.
He even couldn't identify this one.
I came by the shop on my way down home.
Shop owner told me he got it from the Hong Kong Reptile Fair or something.
He even doesn't know the species.
A fellow Korean mania gave me a prompt answer.
It turned out "Keeled Box Turtle".
