人鱼唱月人鱼唱晚
[rén yú chàng yuè rén yú chàng wăn]
It means 'mermaid singing at the dawn of the moon and dusk'. The user might want to imply a sense of romance, longing, and fairy tale-like quality, possibly referring to oneself in a gentle and slightly melancholic light. In many literary contexts, mermaids symbolize distant beauty and unreachable aspirations.
