Last year when I happened searched a mail addr with my full name online, I found a line with a code beside your mail addr from the search result.
I ever used that code many years ago as nick name.
It's big coincidence.
I wrote a mail to that mail addr to ask who she is like.
She is a sensitive girl, ever lived in a city I lived. The Chinese PinYin of our name is exactly the same, character different though.
The reason why we choose the same code maybe because it's prounciated like our family name, it's not a popular one. I should ask her of this.
The girl recently replied again, and I just recall why I sent a mail to here, interesting.
The code is "xenon", looks similar to xeon.
