Who is Cheng Tieniu from?

It is said that in the Tang Dynasty, Cheng married Pei Cuiyun, Pei's daughter, and was the only wife. Pei Cuiyun is Pei's daughter, beautiful as a flower, but she can't get married because of her big feet. She is generous in character, clear in love and hate, and has no miss temper. When she went to kill the crock with her father, brother and younger brother, she met Cheng. Cheng fell in love with her at first sight and wanted to marry her. In order to save her brother, she reluctantly married Cheng. Later, because Cheng didn't dislike her big feet, she really fell in love with Cheng and they became a real husband and wife.

So Cheng Tieniu was born with Cheng and Pei Cuiyun.
