Keep in mind, traditional Chinese culture thinks pretty low of tattoos. Not that that should dissuade you either way, just so you know, most teachers in China would be silently mortified at the idea: they don't see that as a representation of dedication.
However, really, focus your search to what a calligraphy master has done, not a kung fu one. Search for images of calligraphy.
Hopefully someone else may help with some images.
