Another good example should be the introduction of the marketplace business. Last time we mentioned the introduction of the marketplace business, that is, allowing third-party sellers to sell goods on the Amazon platform. In fact, it is a harmful act to Amazon's revenue. Can you imagine McDonald's selling KFC fried chicken? So when this business was launched, it was opposed by many people, not only internal employees, but also Wall Street fund managers, who all said they didn't understand it.

But Bezos said that introducing third-party buyers is the best way to treat customers, because if there is a product whose price or quality is better than ours, then I hope that users can easily buy it on Amazon, instead of buying it.
