I am very curious about why people would randomly select three Chinese characters and tattoo them on.
Here is another example of poorly done tattoo. The top character does not even exist in Chinese characters, and it is completely made up to be look similar to Chinese. The second and third characters are fine, even though I am not impressed with the penmanship, but at least they are are correct and have meanings.
夢 = dream or wish
智 = knowledge or wisdom
