The three-day AI Hackathon trip to Hangzhou completely changed my understanding of the developer community.

From January 16 to 18, I experienced an intense collision of ideas at YunGu Center. During the 72 hours, besides the 12-hour extreme sprint project development, the more valuable part was the gains throughout the process.

The most immediate feeling is that everyone in this community is very different. The seniors have deep technical expertise and project experience, and their way of thinking and problem-solving perspectives often gave me moments of enlightenment. But what impressed me even more was the group of Builders my age. Calling them "shining" is no exaggeration—whether it's their passion for technology, understanding of products, or imagination for the future, they far surpass most of my peers I've encountered before.

During these three days, I gradually understood what "delivery first" means. It's not about releasing only when perfect, but about refining through rapid iteration. This mindset shift may be more valuable than the code itself.

And another unexpected gain—getting to know this group of people. Through project collaboration, brainstorming, and late-night debugging, we built genuine connections. This friendship, born from a shared mission, might be more valuable than competition results.

A new year, new feelings. This hackathon was not just a competition, but more like entering an energetic ecosystem.
