AKA a "flower vase"
A Chinese slang term which often appears in web novels and dramas. An "empty vase" or a "flower vase" is a beautiful person (of either gender) who has no other substance, purpose, or intelligence outside of their appearance (i.e. they have a beautiful outer appearance, but are hollow and empty inside).

Like a vase, they may be chosen to decorate a person's home or life, but can be largely neglected or overlooked, so the term is usually applied to low-maintenance people.

The term is considered a negative insult, and is somewhat similar to the Western concept of a "skin-deep" beauty or a "trophy wife".
