Question:

What does the Korean surname "BYUN" look like in Hanja?

I'm looking to get a small tattoo of my maiden name, but since it looks so plain in Korean, I'm hoping to find a translation into Hanja, the Chinese characters of Korean. My last name is Byun, or alternate spelling, Byeon. Please let me know where I can get a translation or if anyone knows it .. thanks in advance!
