长发及腰系不住君心
[zhăng fā jí yāo xì bù zhù jūn xīn]
'Long hair reaching the waist, yet cannot bind a man’s heart'. Drawing from traditional Chinese literary themes where long hair is often associated with femininity, beauty and even affection, here it symbolically says that despite her charm and efforts symbolized by her gorgeous flowing hair, she can no longer keep hold of his affection.
