History will repeat itself, and the companies that can survive in the next 3-5 years are not simple. From the perspective of the external environment, there is no suspense in the complete decoupling of the Sino-US economy, and the probability is 99.99%. It is not surprising that many enterprises, especially technology-based enterprises, suddenly close down, especially technology companies without independent intellectual property rights. Therefore, every step must take the road of independent research and development, and the popularization of high-end products is the right direction, because the sinking market is becoming more and more involuted, so the logic is here. Xiaomi shouted out the world's first for 3 years, I am afraid it is not a good slogan. It is a company like Huawei, the annual revenue of 2021 has been cut by 1/3, and it is more fortunate that Huawei is not a listed company. If it is a listed company, whether it can be carried in the capital market under such extreme circumstances is a question. It can be seen that some of Duan Yongping's business ideas are still very reasonable. The world is so big, you can pull the egg at any time! Isn't it?
