Song Zhiyan, 29 years old, is a senior engineer in medical device R&D. She holds a number of core patents and is about to be promoted to director of R&D technology—and then she was rejected. It's not that I'm incapable, it's that I'm married and don't have children. "I'm afraid your body won't be able to bear it." Director Liu, who was interviewing her, held a red wine glass and said to a group of people at the industry summit: "Married without children is a time bomb. No matter how capable you are, you can't take it. We are not a charity." He didn't know that she was standing outside the crowd, or that the phone in her hand was recording. He didn't even know that at that moment, a blood-colored writing brush appeared in her palm - the ancient artifact of the law of cause and effect, the Judge's Pen. Three thousand years, three hundred and sixty generations, she is the three hundred and sixty-first. From the job seeker who was rejected to the judge who wrote the trial, what she wants to judge is not just Director Liu, but the gray industry chain that describes married women without children as "risk assets", the academic closed loop that provides theoretical weapons for systemic discrimination, the pregnancy test information leaked by the hospital, and the information shared by the scandal companies The "blacklist of job seekers", the speech that was interrupted three times by male colleagues at the meeting, the hand that seemed to rest on the back of her chair casually at the wine table, the hand that touched her in the crowd in the morning rush hour subway, the small grievances that were not written in black and white but were enough to wear down a woman's life - she wanted to judge them all. The pen is dipped in ink. Page 361 of the Book of Cause and Effect, open.
