永远填不满的处所叫做心脏
[yŏng yuăn tián bù măn de chŭ suŏ jiào zuò xīn zàng]
Literally translates to 'A place that can never be filled up is called the heart'. It suggests the idea of having a deep emotional need or emptiness that cannot be fulfilled, symbolizing a heart that remains unfulfilled or unrequited.
