泪脂
[lèi zhī]
'Lei Zhi' combines the words for tears ('tears') and lip balm/fat ('lip balm'). A poetic way to allude to emotional depth where one is moved enough to cry as if their feelings are oozing out like oils from their lips. It's also reminiscent of historical Chinese makeup practices involving red lip coloring which used lead-fat (an ancient lip balm).
