In "Lin Yuan", the wife of the bandit leader, Aunt Xu, is called a butterfly fan, and she is also a mistress of Zheng Sanpao. She is extremely ugly and tough, with guns in both hands, and men are afraid of her. Lin Yuan describes her appearance like this: "It's really disgusting to talk about her appearance. Her face is a little too long, the width and length are out of proportion, just like a bag of rice hanging upside down around her neck. In order to cover up this sad defect, she combed the lock of hair on her forehead into a long veil and covered her eyebrows, which didn't save her ugliness at all. And that freckled face, with her withered yellow face, is really yellow and black. For this reason, she put on a lot of powder, and sometimes she wiped her eyelids and dropped slag. This tooth was browned by thick smoke, so she simply turned it yellow, so she wrapped it all in gold and smiled. "

There are not many descriptions of butterfly fans in Lin Yuan. She only said her last name was Jiang, but didn't say a specific name. "Butterfly Fan is the daughter of Jiang Sanzi, a big landlord in Xiandong Town ..." It is said that Butterfly Fan is the daughter of Jiang Dazi, a rich man in Hualin Town, Mudanjiang. Although Jiang Dazi has several concubines, he has no children. Jiang Dadaozi then found a woman who sang a ditty called Haitanghong as a concubine in Mudanjiang and gave birth to a daughter Jiang Xiaolan. Nickname: butterfly fan.

Real Butterfly Fan: 1999, Yao Dan (now an associate professor at the School of Arts of China Renmin University) interviewed Qu Bo twice for his doctoral thesis. When she asked about the prototype of the butterfly fan, Qu Bo's first sentence was: "Butterfly fan, very beautiful." When talking about negotiating with "butterfly fans", Qu Bo even added a description: "When butterfly fans went down the mountain, she wore velvet clothes inside and a small pistol and cloak outside; I brought eight guards, boy, I'm coming down. " ("Returning to the Snowfield of Linhai-An Interview with Qu Bo", Historical Materials of New LiteratureNo. 1 issue, 20 12).
