The name of the album "One Grain" comes from Huimin's identification with herself. She used to be sad and cry because her was small (short), and her had no self-confidence. It was not until someone described her with the unit of "grain" that her was a powerful AAA battery, and her realized that this was just an impression her gave to others. That's all. Vivian Chan was very concerned about what others thought of her at the beginning, but later she discovered that a single grain" can be very powerful!
