住进眼睛拥抱背影
[zhù jìn yăn jīng yōng bào bèi yĭng]
The direct translation is 'move into the eyes, hugging the back'. More interpretatively speaking, it means someone who is watching or looking forward to the one leaving, even only seeing their figure going away from oneself, indicating a form of deep longing for parting people or missing someone.
