Idiom story
During the Warring States period, there was a farmer in the state of song who had never seen the world. Because his family was poor, he wore a coarse linen coat all day long and barely survived the winter. The next spring, when the weather was fine, he took off his clothes and exposed himself to the sun. He felt very comfortable. Because he had never seen a beautiful leather coat and a tall house, he told his wife that he would dedicate this heating method to the king.
