today one of my students fed me rice. what she called "oil rice", it's very sticky, not unlike zongzi. the reason for this treat was that someone in the office had a baby, and when it's a month old, the tradition is to feed people this special kind of rice. traditionally you give people this rice if it's a boy, and a cake if it's a girl. but now either is fine. i think it has more to do with which the parents prefer.
