时间说没有过去过去却说还有你
[shí jiān shuō méi yŏu guò qù guò qù què shuō hái yŏu nĭ]
Expresses how time moves on and the past should stay in history; however, memories insistently linger around. In other words, no matter how hard you try to move forward, there's still that person ('you') haunting the memory, emphasizing unresolved past affairs involving specific individuals.
