Even small fireflies can shimmer light in the dark. It is like HKCT alumnus Cheng Hoi-yan gave a complete stranger a second chance at life by giving away part of her liver. Her selflessness attracted widespread media coverage and aroused public attention in organ donation. To commend her virtuous act, two insect scholars named a new firefly beetle species after her: Oculogryphus chenghoiyanae, making her the first Hong Konger that goes into the firefly nomenclature. Let us glow like Hoi-yan and light up life and hope.
