Is it really that difficult for big companies to pivot? Just look at what has happened over the past two years, and you'll understand.

From "technologically ahead, no need to rush" to "the situation has reversed" and then to "full投入," we have witnessed a complete strategic adjustment process of a tech giant. The most impressive part is—the entire transition cycle took no more than two years, yet a complete new system was built.

The core challenges are all laid out: organizational inertia, the constraints of existing product lines, and the pressure from established market positions. These issues have been encountered by large companies, and all have been solved within a relatively short time window.

This case study is worth watching for anyone interested in industry transformation. From defensive to turning around, and then to proactive offense, each stage has lessons worth learning.
