The library in my hometown opened a while ago. I just saw a video posted in the relatives’ group chat. The interior looks quite nice—at first glance, I thought it was somewhere in a major city. I never expected it to be in the small, obscure city where I grew up.

My cousin replied in the group chat: “This is the benefit of living in a city,” which prompted some reflection. When I was little, I had never been to a real library; I could only go to places that sold books, such as Xinhua Bookstore and Hwa To Book City.

Later, when I went to university, the library on campus was left unfinished. It still hasn’t been fully completed from 2008 to this day. The only library at school was a tiny reading room made by knocking together several classrooms. Apart from going in with my roommates to take a look around when the semester first started, I don’t think I ever went in again, because I had other, more suitable places to study on my own.

After graduation, I started working, and the first library I visited was the Guangzhou Library. When I first saw a library spanning several floors, I was still a little stunned. So this was what the place I had always wanted to visit as a child looked like.

I spent some time this afternoon refactoring the F5-Bench project together with Claude Opus 4.6, migrating it from Nuxt to Next.js and switching to Semi Design, developed by the ByteDance team. I feel that this UI library looks even better.

With the help of powerful AI models this time, I optimized the release workflow for the entire project, including various CI/CD processes, version releases, and changelogs. It now looks like a proper open-source project.
