Whenever people ask me: "Where are you from?", I don't really know what to say. "I am from ..., well not quite...", I will usually answer. Like many people, I have never stayed in one place long enough to feel I am really part of one particular group.

Maybe a list of places where I have once lived in might shine some light on the "where are you from" question, so here it goes:
Shanghai -> Dalian -> Shanghai -> Princeton -> Ithaca -> San Diego -> Berkeley -> Pittsburgh -> Philadelphia->Zurich->Philadelphia+Poconos.
