How it's used
Originally referring to a weak physical constitution, this term has expanded to describe anything lacking a solid foundation or substance. When used for people, it implies a lack of vitality or resilience against illness. In professional or academic contexts, it suggests a lack of depth, preparation, or genuine capability.
Examples
They have a weak constitution and get sick all the time.
Your work is so flimsy, how are you going to hand it in?

Common mistake
Do not confuse this with 虛偽, which describes a person who is hypocritical or insincere. While both share the character 虛, 虛底 focuses on a lack of internal strength or quality rather than a moral failing.
