Beijing winters are mostly dry and sunny, so dry you produce static, so hanging washing on hangers in the front room even when it's minus ten out it will be dry by afternoon or next morning if heavy, which is handy with kids - the room is in the "north building" i.e. south facing with big windows of an old-style farm compound. Small bonuses of crappy continental weather system. If it gets above freezing in the day you can stick it out on the line in the yard for a bit to get a freshening finish, the air's OK here because we back right onto the mountains.
