哑巴对聋子说我爱你
[yā bā duì lóng zi shuō wŏ ài nĭ]
Translating as 'The mute confesses love to a deaf person', this phrase creates an ironic and poignant situation suggesting that one's affection is uncommunicable due to insurmountable obstacles or that true feelings are never understood by the other party, emphasizing barriers in expressing one's emotions and feelings.
