姐的眼泪是钻石
[jiĕ de yăn lèi shì zuàn shí]
This nickname 'Sister's Tears are Diamonds' reflects someone with pride and resilience. The implication is that even the tears of this strong individual (perhaps metaphorically) turn into precious jewels, symbolizing that her strength lies in adversity or emotional pain. The term 'sister' gives a feeling of sisterhood, camaraderie amongst females, while comparing tears to diamonds highlights value amidst hardship or sorrow.
