Morning glory and Weaver Girl are the names of two stars. In China, the folk stories about Petunia and Weaver Girl originated very early. The Book of Songs Xiaoya Dadong wrote the morning glory and the weaver girl, but it was only written as two stars. "Spring and Autumn Yuanmingbao" and "Zibo Town in Huainan" began to say that the weaver girl is a goddess. In Cao Pi's Ge Yanxing, Cao Zhi's Luo Shen Fu and Jiu Yong, Petunia and Zhinv became husband and wife. Cao Zhi's "Nine Odes" said: "Petunia is the husband and Weaver is the woman. The star of Vega Petunia is everywhere beside the river drum, and it will be a while on July 7. " This is the clearest record at that time. It can be seen that the story of Petunia and Weaver Girl in the Three Kingdoms period at the end of Han Dynasty has probably been finalized. The Distant Altair is based on the story of Altair and Weaver Girl.
