By Wang Xiaobo When I was thirteen, I often stole books from my father’s bookcase to read. At that time, the political atmosphere was tense, and he had locked away all the books that were unsuitable to be left out in the open. In that bookcase were Ovid’s Metamorphoses, Shakespeare’s plays translated by Zhu Shenghao, and even The Decameron. The case was locked, but my elder brother knew how to pick the lock. He also had a way of persuading me to take the risks: You’re young and slight. I don’t think Dad will have the heart to spank you. But in reality, when it came to spanking me, my father didn’t seem particularly gentlemanly, and my hands and feet weren’t agile enough, always giving him the opportunity. In short, we both read the stolen books, but I was the only one who got spanked. That’s how I got to read some books. Though it was unfair, I don’t regret it. ...

By Qing Jiang I live on the top floor of Building 27. The sun scorches the reinforced concrete rooftop, and the heat lingers until four or five in the morning. As a result, my bed is nothing like those in Guiyang—during the summer, it’s essentially a full-coverage electric blanket. It’s unbearably hot, I fall asleep late, and dawn comes early. The construction workers start their noisy labor early too, so I inevitably wake up early, my pillow drenched in sweat. I’d love to go back to sleep, but the moment I pick up my phone and open Bilibili, I give up on the idea—though I’m still exhausted. So I drag myself out of bed, turn off my phone, sit naked in front of my computer, and start pondering: What do we actually gain from spending so much time on video platforms? ...

Welcome to share your thoughts and experiences. About Myself Verbally, my logic struggles to keep up with my thoughts. I prefer practical work over idle speculation and value genuine experiences over empty actions. I enjoy tinkering with new computer-related technologies, both hardware and software. Over the past three years, I’ve built an integrated system—from sensors to microcontrollers to servers—as part of my thesis. I dislike competing for superficial recognition but still want to prove myself. I’ve participated in two mathematical modeling competitions, never achieving the top rank, but the results weren’t bad either. ...
