This is a story from Strange Tales from Make-Do Studio. Chang Dayong of Luoyang loved peonies very much. He went to Caozhou when he learned that the peonies there were the best of all. He resided in a big garden to wait for the peonies to blossom. When the peonies were budding and redy to blossom， he was already broke， so he pawned all his valuables to wait to see the peonies blossom. One day， Dayong saw a beautiful girl and they fell in love at first sight. The girl followed Dayong to Luoyang and married him. She was Gejin. Later， her younger sister， Yuban， married to Daqi， Dayong's younger brother. One year alter， both of them gave birth to boys. The sisters never talked about their family background. When asked time and again about their father's family， they said，"His family name is Wei and his mother was named Lady Cao." Dayong felt strange at the word because there was no Wei family in Caozhou and moreover， how could such a distinguished family not send people out to find their missing daughters. With these questions in mind， Dayong went to Caozhou again to see the owner of the big garden. He asked the owner whether there was a Lady Cao in the vicinity. The owner took him to a big peony plant and said， "This is Lady Cao."At the work， Dayong began to realize that his wife and her sister were peony flower goddesses. When he returned home， Gejin said to him， "Three years ago， when I saw you loved peonies so much that I was noved and turned into a girl to marry you. Now that you know everything， I have to go."Saying this， she and Yuban， putting the children on the ground， disasppeared. A few days later， two peony plants grew out of the place where the two boys had been put. They bore plate-size beautiful flowers， one in purple and the other in white. That is how the two famous peonies， Purple Gejin and White Yuban took their names. 《聊齋志異》中的故事。洛陽常大用酷愛牡丹。聽說曹州牡丹天下第一，他就跑到曹州，住在一個大花園內，天天等着牡丹開放。待牡丹含苞欲放時，大用已身無分文了，他將值錢的東西和衣服典賣，仍等着看花。一天，大用碰到一豔麗女子，二人一見鍾情，那女子跟着大用回到洛陽，嫁給大用，她就是葛巾。後來，葛巾又把妹妹玉版嫁給了大用弟弟大器。一年後各生一子。二位女郎從不說自己的身世，在大用兄弟再三追問下她們才說：自己姓魏，母親被封爲曹夫人。大用聽了更是奇怪。一是曹州沒有魏姓，二是這樣大的家族丟兩個女兒怎麼沒人找。帶着這兩個謎，大用又來到曹州，找到那座花園的主人，問起當地可有曹夫人。主人領他到一株大牡丹前說：“這就是曹夫人。”大用這才知道自己的妻子和弟妹都是牡丹花神變的。大用回到家後，葛巾告之：“三年前，看到你對牡丹情深，很感動，便變爲女子嫁你，現在你知道真情，我要走了。” 說完和玉版把孩子往地上一放，就無影無蹤了。幾天後，在放兒子的地方長出兩株牡丹，一紫一白，花朵像盤子大，花色豔麗。後人將這兩種名花叫“葛巾紫”、 “玉版白”。
