That’s a very observant question. I wouldn’t say it’s a universal Chinese culture of competition, but rather a reflection of the naive, bubble-like pride we had as children in that specific environment.
We genuinely believed we were special because of the city's status, even if that pride was based on something as shallow as a license plate. It was our way of making sense of our 'elite' isolation. The irony is that this unrealistic sense of superiority made the eventual loss of our home even more disorienting. When the world you thought was the 'center' disappears, you're left feeling completely lost.
