倾城一笑你太天真
[qīng chéng yī xiào nĭ tài tiān zhēn]
The phrase can be translated as 'Your innocent smile could topple cities.' This originates from ancient Chinese poetry, where a charming beauty’s smile was described as being so captivating it could cause kingdoms to fall. Here, it implies that the person addressed is very charming and perhaps naively optimistic.
