The blue costume is a traditional Chinese Yang Guifei fan dance costume, which represents the essence of ancient Chinese culture.
During the Tang Dynasty, Yang Guifei was a beautiful and intelligent woman who enjoyed dancing and singing.
To express their love for her, people created a dance called "Yang Guifei Fan Dance".
This dance requires wearing a blue costume embroidered with flowers and butterflies, which is very gorgeous and delicate.
This costume not only represents the beauty and elegance of ancient Chinese culture but also symbolizes people's respect and worship for Yang Guifei.
