About
The word 卧底 (wòdǐ) is formed by combining two vivid pictorial concepts: 卧, meaning to lie down or crouch, suggesting a hidden, prone, or concealed position, and 底, meaning the bottom or the base of something. Together, they create the powerful metaphor of someone who has "lain down at the very foundation" of an enemy group or organization, visually conveying the idea of an agent who has infiltrated deep into the lowest, most concealed layers to operate secretly from within.
