南以歌北以笙
[nán yĭ gē bĕi yĭ shēng]
‘Song in the South and Flute in the North’ (or similar translations) reflects traditional differences in Chinese regional culture. ‘South singing, North sheng’ describes using different instruments or music styles from the south and north. It can express one's rich cultural knowledge about music, geography, or personal experience of moving between regions.
