I am starting a direct-track PhD at the School of Cyberspace Science and Technology, Beijing Jiaotong University (BJTU). Five years is too long for a single project, so I split the long-running work into separate series, some new and some old, spread across this site.

我刚开始在北京交通大学（BJTU）网络空间安全学院读直博。五年太长，装不进一个项目，所以我把长期在做的事拆成一个个系列，有新有旧，分散在这个网站里。

I study software supply-chain vulnerabilities and constitutional AI across cultures, and I care about learning science and cognitive security.

我研究软件供应链漏洞，以及多元文化下的 Constitutional AI；也关心学习科学和认知安全。

My first camera was a Fujifilm GFX100s, and it is still my only one. I did not work up from a phone or an entry-level body: I committed to a 102-megapixel medium-format system before I had taken a single photograph that justified it.

我的第一台相机是富士 GFX100s，至今也是唯一一台。我没有从手机或入门机慢慢升级，还没拍出一张像样的照片，就有些轻狂地把自己绑在了一套 1.02 亿像素的中画幅系统上。

One body and one focal length keep things clear. With the tool held constant, the only variables left are light, time, and attention.

只用一台机身、一个焦段，事情反而清楚。工具固定下来，剩下的变量只有光线、时间和注意力。

Many photographs here are unedited. Editing matters, but I no longer remember the light and color of those moments, so I have nothing true to edit toward. At most I can rebuild an atmosphere or study the structure. Each photograph keeps a sliver of what I once perceived, even after the memory has faded.

这里有相当一部分照片没有后期。后期很重要，只是那一刻的光线和色彩我早已忘了，没有真实可以对照，我最多能在数字噪点里重建一点氛围，或者看看画面的结构。照片留下了我当时凭直觉感到的一丝真实，哪怕记忆已经散去。

Studio Phantasm is named for the in-between state of every photograph: it swings between hard document and soft fiction, between fabricated memory and forgotten reality. The name also nods to the Phantasm Stage of Touhou Project, whose final boss theme keeps asking the question images have always asked: what is real?

心像图片社的名字，取自每张照片身上的虚实交界：它在冷硬的记录和柔软的虚构之间摇摆，也在伪造的记忆和被遗忘的现实之间摇摆。名字同时致敬《东方 Project》的 Phantasm 关卡，那一关最终 Boss 的主题曲反复追问的，正是图像一直在问的问题：什么是真实。
