Chang Lung was a magistrate during the reign of Chung Tsung and was highly respected for his piety. He spent so much time in the temple, that his son noticed he had started turning into a dragon. Chang Lung confessed that he was intentionally changing so that he could protect everyone, but also that he had been challenged by another dragon. His sons went to help in the fight, but they could only know their father by the red ribbon he wore.
