Once upon a time, there was a girl who had a disabled and nearly blind father in the small town of DOGO. Because of her father’s illness, she always took care of him. One day, she was on her way to bring an acupuncturist as usual. She saw a crane flying down to a small spring and dipping its injured legs in it. On her way back, she saw the same crane dipping its legs in the spring, and again for the next few days. Finally, she saw the crane flying with its healed legs. Seeing this, she took her father to this spring and let him drink the water of it. At last, as the crane was healed, her father’s eyesight got better and his back straightened.
