掌中烛火
[zhăng zhōng zhú huŏ]
It’s a metaphor for fragile beauty and the fleeting nature of life. Literally translated as “firefly flame in palm”, it represents a small yet warm and precious moment held gently in one's hands. Like the weak flickering of candlelight, life and beauty are delicate and may be extinguished suddenly at any time, hence should be cherished while present.
