玻璃瓶里的小精灵
[bō lí píng lĭ de xiăo jīng líng]
Literally means 'Little Sprite in a Glass Bottle'. This evokes imagery from fairy tales about a small, magical creature trapped or living inside a bottle. It has an otherworldly, dreamy, and perhaps melancholic vibe as if expressing desire for freedom and longing for a magical world.
