You should have seen the amount of people that came to the chinese take away I used to work in, asking for names and such in chinese symbols.
Personally I wouldn't want a tattoo that I don't 100% know what it means.
One of my evil minded friends had such a customer in his restaurant, who wanted "Good Fortune" and "Great Wealth" tattooed in chinese symbols, but to his disadvantage, he was a rather annoying and rude customer.
So taking advantage of this, they told him these things.
Weeks later he came back and showed them off, the kitchen staff couldn't help but be very very amused.
Basically what they had told him in chinese was the following
"Gung Hei Fat Choi"
Which is a saying in chinese most commonly used during the new year period and translates as "Happy prosperous New Year".
He was never told what the true meaning was.
Could have been worse
