世界上一切的初恋
[shì jiè shàng yī qiè de chū liàn]
All the first love of the world refers to the collective experiences of initial romantic attraction that have occurred in the world. In a broad sense, 'all over the world' symbolizes universality and infinity, while 'the first love' stands for freshness, innocence, purity, sweetness mixed with some bittersweet moments during adolescence, perhaps bringing a flood of memories of love for readers.
