This word comes from the poem "I won't get married until I'm famous", which contains irony. Luo Yin, the author, used this poem to retaliate against Yun Ying, a prostitute, for mocking her for not getting fame, and mocking Yun Ying, an older prostitute, for not getting married.
Luo Yin, a native of the late Tang Dynasty, passed by Zhong Ling County when he was studying, and met Yunying, a local geisha. Twelve years later, Luo Yin came last again, passing by Zhong Ling, and met Yunying by chance. When Luo Yin saw that Yunying was still a famous musician, she was deeply saddened. Unexpectedly, when Yunying saw Luo Yin, she couldn't help wondering, "Why is Luo Xiucai still wearing cloth?" Luo Yin sighed with emotion and gave a poem to Yun Ying, a prostitute: "Zhong Ling has been drunk for more than ten years and saw Yun Ying in the palm of his hand. I am not famous, I am not married, and I may not be as good as people. " Later, it was said that "Yunying is unmarried" means that the woman is not married.
I hope it helps you!
