西瓜带走了夏天
[xī guā dài zŏu le xià tiān]
The nickname '西瓜带走了夏天' literally means 'watermelon takes summer away'. In Chinese culture, eating watermelon is closely associated with summertime enjoyment; therefore, it suggests memories of good times from past summers marked by enjoying cool, sweet melons - embodying nostalgia over lost periods filled with pleasure.
