她说长大了我嫁你他说长大了我娶你
[tā shuō zhăng dà le wŏ jià nĭ tā shuō zhăng dà le wŏ qŭ nĭ]
'She Said When We Grow Up, I Will Marry You; He Said When We Grow Up, I'll Marry You,' is probably about childhood sweethearts making innocent promises to each other. They may not know precisely what marriage implies at that moment but are sincere when saying these words, showing how pure children can be. This nickname reflects reminiscence over youth.
