智商未成年
[zhì shāng wèi chéng nián]
'Zhi Shang Wei Chengnian' (智商未成年) can be interpreted as having an 'immature intellect,' literally 'Intellectual Underage'. This username could refer to maintaining a kind of naive and childish charm in the world where people usually pretend to be mature and intelligent. It implies lightheartedness or even self-deprecating wit, perhaps hinting someone who is not too caught up in worldly concerns and remains childlike in thoughts.
