Synopsis
At an building, in a room,
the air-con is old, it had been brought to here a really long time ago.
Everyone went out of this room, for their beef about it's so cold and bad mileage
and they work, laugh and talk in a saving-energy room at a moderate temperature.
No one is in this room, but the air-con is not broken,
bad mileage, letting out of really cold air with all its power, do the best .
