On the 10th anniversary of Xiaomi, Lei Jun, the founder of Xiaomi group, responded to the hot issues on the Internet one by one. Unexpectedly, the most incredible and regretful thing for him was that they were the two. Low allocation and high price became a mistake, which offended the supply chain. As one of the top and most popular Internet enterprises in China, the development mode of Xiaomi group can be rated as textbook level. With the shortest time to become the world’s top 500, with their own efforts to become the world’s top five mobile phone manufacturers, but also led the development of intelligent ecology. 2020 is the 10th anniversary of Xiaomi, which is also a turning point for Xiaomi. Lei Jun, the founder of the company, also lamented the ten years of hard work and revealed to the outside world what he most wanted to understand and regretted most. < p > < p > in 2010, Lei Jun, with Xiaomi 1, announced that it had officially entered the smart phone market, and became popular with the price of 1999 yuan. Since then, Xiaomi has been destined to take the cost-effective route, and the hot sales scene has made Xiaomi’s mobile phone in short supply. In just four or five years, Xiaomi has become the number one mobile phone brand in the domestic market. Lei Jun may not have expected that Xiaomi will grow so fast. After winning the championship twice, Xiaomi’s sales declined due to the collective siege from friends. < / P > < p > although Xiaomi’s market share in China is getting smaller and smaller, it can still maintain its fourth position in the world by virtue of its overseas market performance. Not only domestic users are particularly interested in the cost performance ratio, but overseas consumers also quite agree with Millet’s model, and they will definitely choose products with higher configuration at the same price. However, the Xiaomi brand is also constrained by the cost performance ratio, which has impacted the high-end market several times and ended in failure. This is Xiaomi’s biggest obstacle at present, but also Lei Jun’s most helpless practical problem.
