谁还记得来时的路
[shéi hái jì dé lái shí de lù]
It expresses a feeling of estrangement or nostalgia, referring to the passage of time and the distance traveled between then and now both literally and metaphorically. This implies that so much has changed that no one remembers how things once were, possibly speaking on themes of change or forgetting one's origins or初心 (original aspirations).
