chi tun loved cranes. he lived at yang shan east of shan. someone gave him two cranes. as they grew, they stirred their wings trying to fly. chi tun was reluctant to let them go and so cut their feathers. the cranes stirred hopelessly to fly and kept looking at their wings with head haning, much depressed. chi tun said, "since these creatures possess such a noble skyward gesture, how could they be willing to entertain only the eyes and the ears?" when the feathers had grown again, he released them to go.
