"He is, well, Li Jia, a twenty-one-year-old young man. When we first met, we were drinking and having fun in a bar;
He is, um, Mr. Xing Chan, a thirty-two-year-old man. When we first met, he was working as a doctoral supervisor in a university;
She is, um, I don't know, a twenty-seven-year-old woman. When we first met her, she was a waitress in a bar as a graduate student.
That night, Li Jia, who came to the bar to have fun, had sex with a woman she thought was a man. The woman's name was Xu Mingming, and it was indeed unclear. You couldn't figure out what she was thinking, you couldn't figure out what kind of person she was, and you didn't even know what her background was.
On that day, Xing Chansheng, who had just become a doctoral supervisor, was forced to take over a female graduate student who he thought was a boy. The female graduate student was called Xu Qingming. It was indeed unclear. Look at her unclear dress, look at her unclear words and deeds, and you might even mistake her unclear gender.
