你姓陈我姓李我心沉你心里
[nĭ xìng chén wŏ xìng lĭ wŏ xīn chén nĭ xīn lĭ]
'Your surname is Chen and mine Li, my heart descends deep into yours.' This shows that despite differences, the individual's feelings for another run very deep and personal. It’s an expression of love across boundaries such as surnames (Chen and Li) that symbolically stand for different family roots.
