海里多情一条鱼天空凉薄一只雀
[hăi lĭ duō qíng yī tiáo yú tiān kōng liáng bó yī zhĭ què]
Translated, it is 'A sentimental fish in the sea, an unfeeling sparrow in the sky.' This implies the coexistence of deep emotions and indifference between two elements of life, often used in contexts like nature or human feelings, showing complexity in relationships or emotional states.
