The meaning of the song is that a neglected person has to adopt various or even exaggerated methods in order to gain the attention of others.
In this song, Huang Weiwen describes the oppression and persecution of small people by society in an ironic way. The "grandiosity" in the lyrics can be understood as the helplessness of small people in order to survive and develop. They have to exaggerate their own value and sense of existence in order to attract the attention and recognition of others.
At the same time, the lyrics also imply that in this repressive and unfair social environment, even if the little people succeed through hard work, they may only be superficial scenery, but their hearts are full of fatigue and helplessness.
On the whole, Exaggeration presents a social phenomenon that looks gorgeous but is absurd with music, and sings the voices of many small people.
