What did O-lan do to pass the time in the house while Wang Lung worked in the fields?

Wang Lung appreciates all the work O-lan performs around the house, especially given that he once performed her duties himself. Wang Lung is now freed to expend all of his energy in working the fields. O-lan is very resourceful -- she gathers fuel for the fire and fertilizer for the fields without being asked -- yet she hardly speaks a word.
