长发飘飘不及腰
[zhăng fā piāo piāo bù jí yāo]
Literally means 'flowing long hair does not reach the waist', conveying a delicate beauty. Long black hair is a symbol of Chinese female beauty. But the words also express some hidden sorrow - even with such long flowing hair it's still too short to touch the waist, implying there are always things people can't quite reach no matter how hard they try.
