What it is

A platform of adobe or brick with flues through which the smoke of a stove circulates, serving at once as bed, seat and heating. It is the traditional answer to winters in northern China.

Neolithic remains from north-east China are cited, but secure evidence dates from the Han period onwards. Its relation to the Korean ondol (flue heating) is debated: they may be parallel or related traditions.

What it led to

  • family housing with one heated room for sleeping and eating
  • fuel saving by using the smoke from the cooking stove
  • variants in Korea (ondol) and Manchuria
