According to Sina Technology on the morning of January 5, during the "Duan Yongping Alumni Reunion" held at Zhejiang University, Duan Yongping shared an interesting story about himself and Buffett.

During dinner, Duan Yongping and Buffett talked about the business models of Coca-Cola and Apple. "During dinner, Buffett mentioned that he drank PepsiCo when he was young because the price of Pepsi was only half that of Coca-Cola. I said that I think Apple's business model is better than Coca-Cola's. Why do I think Apple's business model is better? I said, when you see the price of Pepsi being only half of Coca-Cola, you will drink Pepsi, but how much difference is there in price between Android and iPhone? You see, real Apple users don’t care at all. He said, 'I got it!' After that dinner, we didn't talk about Apple again."

In 2022, Duan Yongping was invited to attend the Buffett Shareholders' Meeting. "I arrived half an hour early, and there was only one table with two people sitting there, which were Buffett and Charlie Munger. Then a person walked over, it was Bill Gates, and then we four sat down. Buffett introduced me to Munger and Gates, he said: 'This is Ping, he told me that Apple's business model is better than Coca-Cola's, so I bought a lot of Apple!'" Duan Yongping narrated.

Duan Yongping joked, "He bought a lot of Apple (Stocks), this has nothing to do with me, but he still hasn’t sold them all yet, which may have something to do with me, but I don’t know, I have no way to verify this matter." (Yan Yan)
