爱过方知情深醉过才是酒浓
[ài guò fāng zhī qíng shēn zuì guò cái shì jiŭ nóng]
Translated as 'Only after loving can you understand how deeply it feels; only being drunk reveals the strongest drink.’ Reflects mature wisdom about the depths of love and intensity of alcohol consumption, implying both require true experience to comprehend fully.
