时过而不知泪已落
[shí guò ér bù zhī lèi yĭ luò]
'Time passes but unaware that tears have fallen': This name reflects a nostalgic and sad sentiment where the person feels melancholic about the past, perhaps reminiscing over lost moments or regret. The phrase conveys that so much has happened, even causing silent weeping, yet one might not even notice it in the busyness of life.
