Cheng Changyuan was originally the fifth son of the Cheng family in Yancheng. He ran away from home because he was dissatisfied with the "arranged marriage". When he met Cheng Liuyu, a miserable child, he was so kind-hearted that he took a drag bottle with him. The two wandered around and were taken in by a Taoist priest. From then on, they embarked on the road of cultivating immortals and reached the pinnacle of life.
