Why is Cui Yingying also called Wen Shuang?

Mr. Chen Yinque, an academic master, is very good at finding a well-founded history from novels that record brushwork. He wrote Reading the Biography of Yingying more than half a century ago, and speculated that Yuan Zhen's prototype was a "restaurant Hu" woman from Sogdian immigrants in Central Asia. Referring to the three criteria of Hu's surname, Hu's name and Hu's vulgarity, he said, first of all, imagine the original name Cao Jiujiu, because many Sogdians in Central Asia lived in the Central Plains in the Tang Dynasty. Among them, "Cao" people in northern Samarkand, Uzbekistan not only worshipped officials in the Tang Dynasty, but also played the pipa very well, and many people lived in China. Yingying's surname is probably Cao, not Cui. Secondly, Zhou Pu, where Yingying lives, produces the famous wine "Hedong Raisins". At that time, most of the famous grapes in China originated from the Hu people's settlements in Central Asia. The hotel run by Hu people is called "Hu Hotel", and Hu Ji, who is young and beautiful and can sing and dance well, solicits business. Yingying is even more suspected to be Hu of the restaurant. Thirdly, Yingying herself can play music and the piano well, and Hu Ji's artistic characteristics are also faintly visible. In his later years, Mr. Chen Yinque was still thinking about the ethnic origin of Cui Yingying. In the supplement to Bai Yuan's Poems, he further determined that "this female surnamed Cao Jiujiu is almost a Central Asian race". It can be proved that Yingying lived in Zhou Pu, where Central Asian Hu people lived before the Tang Dynasty. However, Mr. Chen Yinque did not regard his many-year hypothesis of "wandering immortals and meditation" as a groundbreaking conclusion, but modestly claimed to talk about it.
