Dont get me wrong, I love the way Chinese and Japanese characters/writing look. That is one of the reason I want to learn it more. But the fact that you had to ask what it was that was on your body, that you yourself didnt know the meaning or could read the characters, means that maybe that tattoo was not a good idea. For all you know it could say something really stupid. For someone who is fluent in the language it might make sense to get a kanji tattoo, but even then, I wouldnt recommend it
