低头看你别抬头抬头看我不低头
[dī tóu kàn nĭ bié tái tóu tái tóu kàn wŏ bù dī tóu]
It has a teasing undertone that roughly translates to 'Don't look up when you look down, I will not lower my head if you look at me.' Here, there are implications of mutual admiration yet hesitation or aloof attitude towards each other.
