南城故瓷北城凉瓦
[nán chéng gù cí bĕi chéng liáng wă]
Poetic expression combining two scenes - 'old porcelain' (often symbolizing something antique and elegant) in the south part of town and 'cool roof tiles' in the north, possibly indicating contrasts between warm reminiscence and cooler reality, tradition and change in different areas.
