An 11-year-old maker at a Shenzhen hackathon.

HiBuddy was built for AttraX Spring, the Shenzhen OpenClaw hackathon held from April 23 to April 26, 2026 at BREWTOWN. AttraX is an outlier community started by students from Tsinghua and Peking University, and the event brought builders together around AI, hardware, art, and cross-disciplinary experimentation.

The theme was Outlier. That mattered to Guoer because she was not coming as a typical hackathon participant. She came as an 11-year-old maker from Shenzhen, carrying a small device, a speech draft, and a question: can a child's idea stand on the same stage as everyone else's?

Guoer comes from Shenzhen Huaqiangbei, where good ideas are expected to become real things quickly. On Xiaohongshu she calls herself Gaoqian Shaonu Guoer, half joke and half attitude: if something is useful and people want it, do not stop at a concept.

At AttraX Spring, the goal was not to give a perfect product pitch. It was to bring an idea into a room full of experienced people, hear what they noticed, and see whether the idea could survive contact with real users, real hardware, and real questions.

Standing on stage with a microphone and the device in hand was part of the work. She had to explain the idea clearly, show why it mattered, and make people understand it in a few minutes.

The audience did not only clap. They asked practical questions: who would use it, how it connects to tools, what can be changed, and whether it could become more than a demo. For an 11-year-old, that kind of feedback was more useful than easy encouragement.

She saw how teams make decisions when time is short: cut what does not matter, keep what makes the demo understandable, and fix the part that blocks the story.

She also learned that building is not just writing code or assembling hardware. It is explaining, listening, changing, and trying again while everyone is still watching.

AttraX Spring gave Guoer a rare kind of classroom: one with mentors, teammates, strangers, deadlines, hardware, bugs, and a real stage.

She left with more than a finished demo. She left knowing that young makers can join serious conversations, that ideas get better when challenged, and that courage is also something you build.
