The truth is, whatever celebrities do has special effects. Everything Du You did caused a sensation in the entire world, and then a kind of herd effect began to develop.
Initially, some people thought Du You's company had good benefits, and they were eager to join. Even when the joining requirements were raised repeatedly, the enthusiasm of these people couldn't be stopped, and there were still those trying hard to join.
Then, it seemed that some people studied something from Du You's success. Some organizations proposed that for an organization to continuously improve, a lot of effort must be made. Only by improving overall can one faster elevate and go higher, thereby driving the entire organization to continue improving, forming a positive cycle.
What they're saying makes sense; the crucial part is that someone actually did this.
Regardless of the outcome, these benefits directly attracted many people to join.
