扎起头发的女孩最揪心披起发丝的女孩最虐心
[zhā qĭ tóu fā de nǚ hái zuì jiū xīn pī qĭ fā sī de nǚ hái zuì nüè xīn]
This means that girls with tied-up hair are touching while those with loose hair deeply move one's heart; it refers to feelings evoked by different styles of how females wear their hair. The former reflects an image of energy and activity; the latter conveys an atmosphere full of grace and melancholy.
