Just caught up with a recent interview where Duan Yongping shared some fascinating perspectives on investing and life. The guy's been in the game for 20 years with a net worth estimated around 30 billion USD, and honestly, his core ideas are worth revisiting more than once.

What strikes me most about Duan Yongping's philosophy is how he frames the fundamentals. He keeps hammering on one point: buying stocks means buying a company. Sounds obvious, but he's right that most people don't actually operate this way. It's not just about understanding the business either—it's about the depth of that understanding. That's your real safety margin, not some arbitrary price-to-book ratio. The margin of safety isn't a number; it's how well you truly know what you're buying.

His take on decision-making is equally sharp. He uses this punching machine metaphor—in a lifetime, you only get about 20 good punches, so each one matters. He's thrown less than 10 so far and still sees plenty of opportunities ahead. That's the mindset of someone who doesn't chase every trend. It also means knowing when to sell, which he emphasizes is actually the hardest part. Too many people confuse value investing with forever-holding. If fundamentals shift or better opportunities emerge, you exit. Period.

What's interesting about Duan Yongping's corporate philosophy is his obsession with culture over everything else. He talks about how BBK's strength now isn't because he's still running things, but because the culture is embedded. The CEOs at OPPO and vivo don't ask 'what would A-Duan do?'—they ask 'is this right for the user?' That's delegation done right. It takes time to build, and it's not something you just announce; you live it until people internalize it.

On life philosophy, he's surprisingly reflective for someone so accomplished. He stresses that security in childhood shapes everything—kids with genuine security explore more, fail better, and develop real independence. He also advocates for doing what you love, which sounds cliché until you realize he actually means it. No passion means no excellence. Age, skills, background—these can all be learned. What matters is the drive.

His thoughts on AI caught my attention too. He doesn't see it as a threat but as a tool. AI boosts efficiency and frees people from repetitive work, but it can't replace human judgment. The future belongs to those who master the tools while staying curious. That resonates with me—we should embrace new tech rather than fear replacement.

What I'm taking away from Duan Yongping's wisdom is this: excellence comes from doing simple things seriously. Whether it's investing, building a company, or living life, consistency and depth matter more than activity. He's 65 and still talks about having many opportunities ahead because he never stopped learning. That's the real edge.

I'm planning to keep exploring blockchain for the next several years too. Let's keep learning together and applying these principles to whatever we're building.
