情久会腻情深难敌
[qíng jiŭ huì nì qíng shēn nán dí]
'Qing Jiu Hui Ni Qing Shen Nan Di' (Love Grows Old And Deeply Unmatched). The longer you stay in love, the more bored it may become, but true deep love will always endure any challenge and remain unbeatable. It expresses mixed feelings regarding relationships—both their challenges and strength.
