前面的刘海长那么快后面的头发也学着点
[qián miàn de liú hăi zhăng nèi me kuài hòu miàn de tóu fā yĕ xué zhe diăn]
In a humorous way, this refers to the different growth rates of bangs versus the rest of one's hair. It conveys lighthearted frustration with uneven hair growth or difficulty maintaining an ideal hairstyle.
