Jasmine or Jasmin**
1. It can be shortened to Jas by friends.
2. Doubt anything funny can be made out of it.
3. It's the name of a flowering shrub and the flower smells nice.
4. It has a Asian/Arabic context so ppl from those races won't find it
un-familiar.
5. It makes a good fit with your Chinese origin. That's a assumption
though since i don't really know how you look, but in either case it
ain't too bad
