= Company Moths
公司驻虫 (gōng sī zhù chóng).
公司驻虫 are young, white collar workers whose lives revolve around their company. They get off work very late and have little desire to be at home. Every step of their daily routine — eating, working, resting, socializing, and even dating — all occurs near the office.
The term is actually a play on words. 公司驻虫 itself doesn't actually mean 'company moth' but it sounds identical to the phrase that does- 公司蛀虫 (gōng sī zhù chóng)”.
