So here, I’ll shamelessly piggyback[1] on the fame of my old university classmate, Liang Wenfeng. Some netizens wanted to know what Liang Wenfeng was like during his undergraduate years before he got into investment and the AI industry, so this answer is to satisfy a little bit of that curiosity. I hope these “revelations”[2] won’t affect Mr. Liang’s privacy. If they do, please remind me, and the author[3] will modify or delete the post.

Although we had some contact during our four years as classmates, we weren’t in the same dorm or class, so my impressions of him are limited and fragmented. Impression 1: In our sophomore year, while the rest of us were dutifully attending classes, doing homework, and preparing for exams, Liang Wenfeng was already self-studying digital and analog circuits and had started his own engineering projects. What left a deep impression was that he handled everything himself—from circuit design, PCB, and microcontroller programming to creating a UI for software similar to a mini-player (back in 2004, creating a software UI was a highly technical skill). He modified a regular guitar into an electric one, where the guitar’s sound effects could be controlled via a UI on the computer. This design seemed incredibly impressive at the time; we all said “Wow!”[5] when we saw it. He humbly said t
