摩天轮式的幸福旋转木马的悲伤
[mó tiān lún shì de xìng fú xuán zhuăn mù mă de bēi shāng]
This name contrasts the happiness represented by the Ferris wheel and the melancholy of a carousel, both attractions that symbolize fleeting or unattainable happiness in romantic contexts. It implies that what seems happy from outside can hide underlying sadness, as often used to convey mixed feelings or nostalgia.
