Despite the many positive reviews which can be seen on the Internet (see the PrintScreen below), this tattoo is not a "cool Hanzi tattoo" or a "Chinese symbol tattoo" or a "cool wrist tattoo" or anything else of this kind. In fact this is nothing else than another failed Kanji/Hanzi tattoo drawn by someone who doesn't know anything about Chinese/Japanese writing.
And definitely this deformed ideogram does not mean "bike", as some people think, despite the fact that the ideogram is so poorly written that it looks more like a severely damaged bike rather than the original ideogram (成 - Chinese pronunciation:"chéng", japanese pronunciation:"naru/nasu/joo/sei"; meaning: "to finish / to complete / to accomplish / to become / to turn into / to change into"). In the image below you can see what this ideogram should look like:
In the end I have a piece of advice for the guy who wear this tattoo: dude, if you want to be the change or to be a part of the great change (as your tattoo suggests), you should start the change with this ridiculous tattoo.
Stupidity is painful
Another failed kanji / hanzi tattoo
A cool guy... or a bad woman?

Don't believe this guy - he has no idea what he's talking about:)
This is NOT a Kanji / Hanzi tattoo. This is just a doodle.
What possibly could be wrong with this tattoo?
