阳间幕宾
[yáng jiān mù bīn]
In Chinese culture, '阳间' (Yáng jiān) means where humans live - as opposite to where spirits reside in afterlife. '幕宾'(Mù bīn) stands for a type of advisor in ancient Chinese government offices who was in charge of managing various documents and advising superiors. Together, it refers to someone working behind the scenes in the 'real world', possibly alluding to being understated or low-key in modern society
