一见钟情钟的是脸日久生情钟的是心
[yī jiàn zhōng qíng zhōng de shì liăn rì jiŭ shēng qíng zhōng de shì xīn]
This means 'Love at first sight falls for beauty, but true love grows over time because of the heart'. It describes the progression from surface attraction to deeper, more meaningful affection developed through long-term familiarity and interaction.
