Photograph by A.Segers DINNER MAY GET COLD, BUT THE DINERS KEEP WARM BY SITTING ATOP THE FURNACE, SOON TO BE THEIR BED! The heating plant in taverns and homes of North China is built of masonry and warmed in winter eitherby afire on theinside orbyaflue passing through it from the kitchen. After dinner, family and guests remove the low tables, place mats on the hard, hot surface, and "turn in" side byside, resting their heads on small, hard pillows stuffed with millet. In cold weather the whole row of sleepers is covered with along, wadded coverlet.
