How it's used
Refers specifically to the soft spot on an infant's skull, but is most frequently heard in the idiomatic expression 腦囟都未生埋. This phrase is a common, slightly harsh way to criticize someone for being naive, childish, or lacking life experience. It implies that the person is still essentially a baby in terms of their mental development.
