一笑倾城哭倒长城
[yī xiào qīng chéng kū dăo zhăng chéng]
'A Smile That Can Dazzle the City; A Cry That Can Bring Down the Great Wall' comes from ancient legends about exceptionally charming and influential beauties who have had powerful impacts on their environments, symbolizing someone's ability to strongly move others with emotion and charisma.
