When the son of the sky came down to the earth, he suggested that Hyeokgeose has to find good wife for him. At that time, Gyeryong (계룡), which is a dragon looked like rooster, came down from the sky to Alyeong-jung (알영정) in Sarang-ri (사량리) and bore a beautiful girl who had chicken beak under the dragon’s left rib. When people moved and washed her at Bookchun (북천) in Walsung (월성), the beak chipped off. So the people called the place Balchun (발천) and named her Alyeong.
