北湾旧巷
[bĕi wān jiù xiàng]
It refers to a place in one's memory where '北湾' (Beiwan, which means Northern Bay, but doesn't specifically refer to an actual geographic location here) symbolizes the north, which traditionally has been seen as distant or isolated. '旧巷' (old lane) adds a flavor of reminiscence and nostalgia for old times and things.
