What does “A nine days wonder” correspond to in Chinese?

A nine days wonder: a person or event that attracts a lot of notice and is the subject of much talk for a short time but is soon forgotten. It corresponds to “昙花一现"in Chinese. The English idiom is somewhat descriptive, while the Chinese one is mainly figurative, alluding to broad-leaved epiphyllum, a plant whose beautiful flowers last briefly.
