Anyone who has seen ancient costume films knows that the official rank of Qing officials is reflected by the flower feathers they wear. Flower feathers are made of peacock feathers, which was a symbol of distinguishing rank and prestige at that time. In western countries hundreds of years ago, they also expressed someone's achievements or honors through feathers inserted in their hats.

It is said that Hungarians put a feather in their hat every time they destroyed an enemy, so the more feathers there are in the hat, the braver and more respectable that person is. This tradition has also been recognized in other countries. Later, people used it as a metaphor for honor and achievement.
