It is "Telling a Nightclub Story of a Little Girl in a Third-tier City" on Zhihu
Excerpt from the content: She asked me, have you ever seen a young lady. Of course I am no longer the innocent boy I was when I just left school. I told her honestly no. Then he showed some pride unnaturally. Then, I told her that I often read about police catching prostitutes on the Internet. Seeing the embarrassment of their escape, it was really colorful. Now think about it, _Si is _ Si, she just doesn’t know how to chat. When I told a girl about the police, I didn’t expect that she was very good at chatting. She took the conversation naturally. I was also arrested by the police. Then she told me a story about being arrested while doing field work.
