It is because the people of the Dragon Country possess their own national confidence.
When the people of the Dragon Country see a fashion model from a certain academy strut the runway catering to Western aesthetics, they will curse, but when they see a model showcasing Hanfu culture, they will praise.
Deep down, there is an appreciation and aesthetic for their own country's offerings.
With the rise of the Dragon Country, its people have long ceased to believe that the air elsewhere is sweeter than that of their own country.
In the past, if someone had claimed that the air in other countries was sweeter than in the Dragon Country, it's likely some would have been swayed.
But in this era, if anyone were to make such a claim, they would likely be scorned by all the people of the Dragon Country within minutes, even deemed brainless idiots.
Every citizen of the Dragon Country hopes for the betterment of their nation's offerings.
