Leo Ying

I left behind school days that ran from 5:30 a.m. to midnight, and built my own way to learn.我离开了从凌晨 5:30 排到午夜的学校生活，搭建了自己的学习方式。

I’m Leo, a high school student from a small town in China. Inside ChatGPT, I built Learning Lab and gave it one rule: after every session, re-read the whole conversation and check both my answers and its own teaching. With it, I relearned chemistry from almost zero. I passed the chemistry exam I needed to graduate 14 days after my first diagnostic.我是 Leo，来自中国一个小镇的高中生。我在 ChatGPT 里搭建了 Learning Lab，给它定了一条规则：每次学完，都要重读完整对话，核对我的作答和它自己的教学。我用它从几乎零基础重学化学。第一次诊断之后 14 天，我通过了毕业必须通过的化学考试。

See Learning Lab看 Learning Lab Read my story读我的经历

My real school day. The gaps are the breaks.我真实的在校作息，空隙是课间。

I didn’t let that environment make me just like everyone else. I knew what suited me, even though I was definitely the odd one out.我没有被环境同化。我很清楚什么适合自己，尽管我绝对是个异类。

For a long time, this was my day. Up at 5:30.很长一段时间，这就是我的一天。5:30 起床。

I often couldn’t follow the lessons.上课常常听不懂。

Just as something started to make sense, the next class began. There was no time to practice.刚理解一点，下一节课就开始了，没有时间练。

Every evening, about two hours of exams.每天晚上，约两小时的考试。

Bad results, again and again, on things I hadn’t learned yet.还没学会，就一遍遍拿到糟糕的结果。

Classes and study hall until 10:30 p.m.上课和自习排到晚上 10:30。

Not asleep until around midnight.十二点左右才睡。

Classes on Saturday, exams all day Sunday. Just two and a half days off a month.周六照常上课，周日全天考试。一个月只放两天半。

This isn’t just my story.这不只是我一个人的经历。

Classes and exams fill the whole day, and there’s rarely time to work out what you didn’t understand.课程和考试把一天排满，没学懂的问题却常常来不及解决。

I tried to adapt. This way of learning didn’t suit me.我试过适应。这种方式不适合我。

In my final year, I stopped going to class and studied at home. The exams were still ahead.高三这年，我不再去学校上课，在家自学。考试还在前面。

No one around me supported it.身边没有人支持。

What I wanted most was to breathe freely and walk out of a life where even my time wasn’t my own. I wanted my questions taken seriously and my situation taken into account. I wanted real progress, and hope.我最希望的，是能自由呼吸，从那种连时间都不属于自己的生活里走出来。我的问题能被接住，我的情况能被照顾，有真实的进步，能看到希望。

Leaving school made me a sunnier person. The day still had twenty-four hours, but now I learned at my own pace and lived the way I chose.离开学校让我变得阳光。一天还是二十四小时，我终于能按自己的节奏学习，也按自己的想法生活。

Nothing yet proved this path would work. So I built a place where my questions would be taken seriously: Learning Lab.还没有任何结果能证明这条路行得通。于是我搭了一个能接住我的问题的地方：Learning Lab。

How Learning Lab worksLearning Lab 怎么运行

The real exam decides what I learn. My own learning record decides how I learn next.真实的考试决定学什么，我自己的学习记录决定下一步怎么学。

  1. ME我

    Set the goal定目标

    SEP 19 月 1 日

    The goal: pass the exam on September 19.目标：9 月 19 日通过考试。

  2. ME我

    Do the problems first and let the gaps show先做题，把不会的地方暴露出来

    SEP 59 月 5 日

    First diagnostic: done in twelve minutes, because I could do almost none of it.首次诊断：十二分钟就做完了，因为几乎都不会。

  3. CHATGPT

    Teach; explain it another way if I say it isn’t working讲解；我说不管用就换讲法

    SEP 179 月 17 日

    I said, “After you expanded on it like that, I’m even more confused,” and it changed how it explained.我说“你这样展开之后我更不清楚了”，它换了讲法。

    Translated from Chinese · Show original

    “你这样展开之后我更不清楚了”

  4. AUDIT, BY MY RULES审计，按我定的规则

    Re-read it all; check my answers and its teaching重读完整原文，核我的作答和教学

    SEP 139 月 13 日

    In the session: I solved it my own way, then it suddenly switched topics and broke my train of thought.课上：我用自己的方法做对了，它却突然岔开去讲别的，打断了我的思路。

    After the audit: The session had already confirmed my method. The audit saved the correction to my learning record and told future lessons to keep it.审计后：课上已经确认我的方法没错。审计把这次纠正记进学习记录，要求后续教学保留这个方法。

  5. CHATGPT, AS I ASKED，按我的要求

    Update my status, reports and review schedule更新状态、报告和复习安排

    SEP 189 月 18 日

    It planned 90 minutes of review before the exam. I worried that would drain me for the afternoon exam, so it cut it to 30 minutes at most, in the morning.它原定考前复习 90 分钟。我担心耗掉下午考试的状态，它改成上午最多 30 分钟。

  6. NEXT SESSION下一次

    Practice last time’s mistakes first先练上次错的地方

    SEP 199 月 19 日

    The exam-day warm-up started with the kind of question I’d gotten wrong the day before. This time I got it right on the first try.考前热身先练前一天做错的那类题，这次一次做对。

The night before the exam, I wrote: “Studying with you has also brought back that state where I can really understand, where I can keep moving forward.”考试前一晚，我写下：“跟你的学习呢，也让我找回了那种真正能学得懂的状态，能推进的状态。”

NOW现在

Learning Lab is built for learning and exam prep in general. Chemistry is its most fully recorded use so far. I also make short explainer videos with AI. In both, I use my own data to keep improving how I work.Learning Lab 面向更广泛的学习和备考，化学是目前记录最完整的一次。我也在用 AI 做知识短视频。在这两件事上，我都用自己的数据，不断改进做法。

I’ve trained regularly since I was 12: strength four times a week, road cycling on the other days. I’ve had several surgeries for a collapsed lung (chest drainage and thoracoscopy), and I never gave up training. I use ChatGPT to plan my training and analyze the data, too.我从 12 岁开始规律训练：每周 4 次力量，其余几天公路骑行。中间做过几次气胸手术（引流和胸腔镜），我依然没有放下运动。训练计划和数据分析，我也交给 ChatGPT 来做。

“我觉得我现在很大的问题实际上是不知道自己的问题在哪。”

So I built Learning Lab with ChatGPT’s Projects feature. It holds my goals, learning status, reports and review schedule, so my learning carries over from one conversation to the next. I keep changing it based on how well it actually works for me.于是我在 ChatGPT 的 Projects 功能里搭建了 Learning Lab：里面存着我的目标、学习状态、报告和复习安排，让学习能在不同对话之间接上。我根据它实际好不好用，不断修改它。

In ChatGPT it’s called “高考学习重建｜Learning Lab,” which means “rebuilding how I learn for the gaokao.”它在 ChatGPT 里的名字是「高考学习重建｜Learning Lab」。

It notes what went wrong and how far it got fixed, then updates my learning status and review schedule. The next session starts from there.我给它定了一条核心规则：每次学完，Lab 重读完整对话，把我的作答和它的教学放在一起核对；记下哪里出了问题、解决到什么程度，再更新我的学习状态和复习安排。下一次就从这里开始。

I asked it to redo the full-record audit and actually make the improvements, not just point out problems and then change nothing.我要求它重新做一次原文审计，而且要把改进真正做出来，不能只提出问题，之后什么都不变。

It has to read the whole record. If it sees only that I got something wrong, a teaching problem can get logged as my weakness. If it sees only that I got it right in the end, something I did only after hints can get logged as mastered.必须读完整原文：只看到答错，可能把教学的问题记成我的能力问题；只看到最后答对，又可能把提示后才完成的记成已经掌握。

SEP 59 月 5 日

An answer handed to me doesn’t count送到眼前的答案不算数

It asked how many elements were in a formula, when the answer was already in its own notes. I said: “Actually, you already told me.” The audit later made this a rule: a question that hints at its answer doesn’t count as evidence that I’ve learned something.它问我一个化学式里有几种元素，答案就写在它自己的笔记里。我说：“实际上你都跟我说了呀。”审计后来把这定成规则：暗示了答案的题，不算我学会的证据。

    “Of course there are two elements, calcium and chlorine… Actually, you already told me. Your notes already say Ca is calcium and Cl is chlorine, so obviously there are two.”“当然有两种元素，分别是钙元素和氯元素……实际上你都跟我说了呀，因为你的笔记当中已经写了Ca等于钙，Cl等于氯，那所以很显然有两种。”

    Agreed the question tested almost nothing, and switched to one that mattered: the ratio of Ca to Cl.承认这题信息量太低，改问真正有用的问题：Ca 和 Cl 的数量比。

  3. The audit later made this a rule: a question that hints at its answer doesn’t count as independent evidence that I’ve learned something.后来的审计把它定成规则：暗示了答案的题，不能算作我学会的独立证据。

From the audit of my September 5 session:9 月 5 日那次学习的审计：

  1. 1. Questions gave answers away or repeated, so I got more right than the real evidence showed.题面泄露与重复，使正确次数高于有效证据量

Chemistry in 14 days14 天的化学

Chemistry isn’t one of my gaokao subjects, but I had to pass the chemistry Academic Proficiency Test to graduate. My basics were extremely weak; I had to relearn atoms, molecules, coefficients and subscripts. Learning Lab was brand new and still rough. From my first diagnostic on September 5 to the exam on September 19 was 14 days. I studied while building and fixing the Lab.化学不是我的高考选科，但毕业必须通过化学学业水平合格性考试。我的化学基础极弱，原子、分子、系数、下标都要重新学。那时 Learning Lab 还刚搭起来、很不成熟。从 9 月 5 日第一次诊断，到 9 月 19 日考试，一共 14 天。我边学、边搭、边改。

On Douyin I came across a new, fast-growing category called “vibe 知识大赏” (roughly, “vibe knowledge showcase”): explainer videos made with AI. AI has made knowledge cheap to get, and social media has made it far easier to reach people. I saw the opening and started my own account.我在抖音上看到一个新兴的板块“vibe 知识大赏”：用 AI 做知识类视频，而且很火。AI 让获取知识变得廉价，自媒体让传播门槛大幅降低。我看准了这个机会，开始做自己的账号。

      “Is this a real review? Did you get real data? I don’t think I’ve given you any yet. How did you do the review?”“是否是真实复盘？你拿到真实数据了吗？我似乎还没有给你，你如何做的复盘？”

      Translated from Chinese · Show original

      “是否是真实复盘？你拿到真实数据了吗？我似乎还没有给你，你如何做的复盘？”

    2. WHAT CHANGED改了

      Split the work: ChatGPT collects the platform data 24 hours, 48 hours and 7 days after each post; Claude analyzes it.定下分工：ChatGPT 在每条发布后 24 小时、48 小时、7 天采数据，Claude 负责分析。

  3. OCT 24–2610 月 24–26 日

    1. ME我

      I didn’t post a video that night; I didn’t think any of the finished ones were good enough. I said Claude and I could throw out our old format, so our past work wouldn’t limit us.那天晚上我没有发视频，因为觉得做好的几条都不够好。我提出，我和 Claude 可以推翻之前的形式，不被自己的过去限制。

    2. WHAT CHANGED改了

      Held back four finished videos and switched to mostly my own topics.已经做好的四条片子不发，改以我自己的选题为主。

  4. OCT 2910 月 29 日

    1. DATA数据

      Each time a new example started, more viewers dropped off. The AI’s analysis suggested using only one example per video.每换一个例子，观众流失得更快。AI 的分析建议：一条片只用一个例子。

    2. ME我

      “Only one example per video… isn’t that too extreme?”“一条片子只用一个例子……会不会太极端了？”

      Translated from Chinese · Show original

      “一条片子只用一个例子……会不会太极端了？”

      I thought there might be more than one factor.我认为影响因素可能不止这一个。

    3. WHAT CHANGED改了

      Each video hangs on one main question. It can use more than one example, as long as they all answer it.一条片只悬一个主问题，例子可以不止一个，但都要回答它。

Same Smoke

Made during the transboundary haze over Singapore and Malaysia. Scattered news merges into “the same smoke,” then five time scales carry it, step by step, into the body. No narration. English came first, then Chinese and Malay.做于新马跨境烟霾期间。零散的新闻汇成“同一片烟”，再用五个时间尺度把烟一步步带进身体。没有旁白。先做英文版，后来又做了中文和马来文版。

I care about social issues and want to speak up about them. Each of us has a responsibility to make society better.我关注社会问题，也想为它发声。我们每个人都有责任让社会更好。

What I asked for我提的要求

  • Powerful and memorable, but built on science.要震撼、有记忆点，但必须以科学为根本；
  • Not a government PSA, and not ordinary popular science.不要做成政府宣传片或普通科普；
  • Something that sparks discussion, not controversy.要引起讨论，而不是争议。
