The theory of the relationship between Fuxi and Nuwa should have existed in the Eastern Han Dynasty. The famous precepts of Zilan in Huainan recorded the myth that the goddess filled the sky. Its author is Liu An, a native of the Western Han Dynasty. He didn't talk about the marriage relationship between Nu Wa and Fuxi in his works. Gao You, a native of the Eastern Han Dynasty, said in the annotation of Huai Nan Zi that Nu Wa, Yin Di and Zuo Fuxi were also rulers. The marriage relationship between Nuwa and Fuxi has not been mentioned so far. When talking about Fuxi and Nu Wa, Huangfu Mi of A Jin Dynasty never forgot to talk about their marriage relationship. According to Meng's textual research, in the late Tang Dynasty, the concept of Nu Wa marrying Fuxi was still in the process of formation. It was not until the late Tang Dynasty that they were kneaded into a pair. [
