手牵手一起看海背靠背一起怀念
[shŏu qiān shŏu yī qĭ kàn hăi bèi kào bèi yī qĭ huái niàn]
Meaning 'holding hands watching the sea and back-to-back reminiscing together.' It evokes a picture of intimacy, fond remembrance of past good times. There are moments of closeness (holding hands while watching the sea) contrasted with moments when people are apart (back-to-back) but still cherish past experiences together.
