You can call me...
My parents called me "May May" growing up which is just the second part of my name doubled, which shows endearment in Chinese, but it also means "little sister" in Chinese. I'm an only child.
In high school when we first started hearing about Email, my friend Tiffany started calling me "YiMail" and then "Emay" which somehow transformed into "ThetaMay" because we were in geometry class and learning about theta (θ) which kind of looked like an "e". Anyways then "Yi", just the first part of my name came out of that. A lot of people call me "Yi" now and that's how I sign my emails and use for usernames on sites like Vox.
In college the "YiMail" thing started all over again, but luckily the guy that started it everyone just found annoying so it didn't stick.
When Ebay showed up some people at work called me "Yibay". That didn't last very long though because when you said it it just sounded like you were saying Ebay which was no fun and confused people.
Some people occasionally call me by my last name which is very high school coach-like. I find it annoying.

The only chinese I remember from childhood -- and quite vaguely -- is the following: moi moi (little sister), jhe jhe (big sister), and go go (big brother). Cantonese, not mandarin.
