久旱逢甘霖的遇见
[jiŭ hàn féng gān lín de yù jiàn]
Means 'Meeting like a timely rain after a long drought.' It metaphorically describes encountering someone or something very welcome when you've been in dire need for it, akin to receiving much-needed rain during prolonged dry spells, signifying hope, relief, and rejuvenation.
