纤屑

纤 = 千 + 纟 : Marie Curie (xi) finds that there are many fine (纤) silk worms (纟) in front of the anthill (a1). She wants to preserve the delicate (纤) worms and thus puts a kilo (千) on them to press and dry them.

屑 = 尸 + 肖 : Marie Curie (xi) and the little prince (肖) are frequently visiting a ghost (尸) in the elevator's bathroom (e4). The ghost is feeding on their dandruff (屑), therefore it's a win-win situation for all of them, but secretly they feel it beneath their dignity (不屑).
