Can anyone give me more information about the 천혜향?

I tried a new fruit from Jeju recently. A friend of my wife's whose home town is on Jeju sent her a box. It is called a 천혜향 (cheon hye hyang). My wife says it's a new crossed between a hallabong and a tangerine. I looked for information in English online, but apparently it is so new there is no info in English online yet. Can anyone give me more information about this delicious fruit? I mean, I'd have to say it's one of the best fruits I've ever eaten. I can only describe it as a large tangerine shaped fruit that is extra sweet with a gfruit kick to it. The peel doesn't come off as easily as a tangerine either. Any info would be appreciated!
