南城旧忆北城旧样
[nán chéng jiù yì bĕi chéng jiù yàng]
This netname reflects a sense of nostalgia mixed with contrast; recalling memories (memories belong to the past, something old) from the southern part while the current state remains unchanged in the north, evoking a poignant mix of remembering good ol’ days versus what has become unchanging reality.
