蓦然回首那人早已结婚生子
[mò rán huí shŏu nèi rén zăo yĭ jié hūn shēng zi]
Based on a classic line from ancient Chinese poetry ('suddenly turning around'), this name reflects a moment of bittersweet nostalgia where a person realizes too late that someone they once knew or cared for has moved on, got married, and started a family.
