It comes from the poem "I am not yet famous but you are not yet married." This word contains an ironic meaning. The author Luo Yin used this poem to respond to the prostitute Yunying's ridicule for not having achieved fame and mocking the older prostitute Yun. Ying is not married yet.
This falls into Luo Yin’s seven unique poems:
Zhong Ling was drunk for more than ten springs and saw Yunying’s upper body again; I have not become famous and you are not married, so maybe both It is inferior to others.
In "Tang Poems", the title of the poem is "Gift to the Prostitute Yunying" (I guess this title was added by later generations). There is a footnote after the poem: "Yin came to the imperial examination and met Yunying, an old prostitute. Yunying said: 'Luo Xiucai has not yet shed his virginity! Because he gave me a poem." According to today's words: Luo Yin failed in the imperial examination and met his old sweetheart. Yunying, a prostitute, said, "Luo Xiucai, you haven't taken off Bai Ding's hat yet!" Luo Yin wrote this poem as a gift to her. It can be seen that Luo Yin was in despair before going to Wuyue. By the way, Xiucai is an honorific title for scholars who enter school, not a first-class academic title, so Luo Yin is still Baiding.
In the thirteenth year of Dazhong (859), Luo Yin paid tribute to the capital for the first time in Nankang County. Passing by Zhongling, I dined with the prostitute Yunying. Twelve years later (871, the twelfth year of Xiantong), when he saw that the Ministry of Rites had been deposed and was on a desperate journey, he met Yunying again in Zhongling. Feeling deeply about his life experience, he wrote his masterpiece "Mocking the Prostitute Yunying in Zhongling": " After being drunk for more than ten springs, Zhong Ling saw Yunying's body again. I am not famous yet, but I am not married, so I may not be as good as others. "This is why "Yunying is not married".
