小巷未改旧人未归
[xiăo xiàng wèi găi jiù rén wèi guī]
The literal translation would be: 'the narrow alley remains unchanged while the old acquaintances haven’t returned yet’. It hints at the unchanged place still preserving past memories but those who once walked this path (representing friends/loved ones) are absent now, which brings a kind of poignant nostalgia, longing for reunion with people of significance to return to this location again.
