The capital market is the most sensitive, and we need to learn to analyze problems from a capital perspective. For example, is BYD better or Tesla? Compare their market capitalizations. For instance, is Japan declining or rising? Look at global capital voting. Chinese smartphones are so impressive, so why is the combined market cap of all domestic enterprises not even comparable to Apple's? That tells us what we're seeing is not the truth. For cars, phones, and all major purchases, there's just one principle: buy global models and don't spend more money on inferior products. Just remember one principle: whatever they use, we use. And this "they" refers to that "they." Not us.
