不及眉间朱砂尽
[bù jí méi jiān zhū shā jĭn]
Literally translated as 'not comparing to the cinnabar between eyebrows', this implies that something or someone cannot be as enchanting or unforgettable as the love spot represented by a speck of red cinnabar between the brows. The cinnabar mark traditionally symbolizes beauty, passion, and destiny.
