One of the representatives sent by the French Vogue International Jewelry Association was named Mr. Jill de Castei. He was from the de Castei aristocratic family.
Although the aristocratic system had become obsolete in France, the aristocrats who were minted during the French monarchy and empire period had a rich cultural history. Hence, they were often the center of attention during most social events, because of their posh and noble vibe. Hence, the French still looked up to the aristocrats.
The Wen Family was informed of Mr. Jill de Castei's arrival as soon as he checked into the luxurious hotel and immediately sent their staff to welcome him politely.
After all, the French Vogue International Jewelry Association was extremely reputable in the world and they definitely had to show Mr. Jill de Castei due respect, though there was no need for them to suck up to him since he was there to visit them. It would be inappropriate for them to lose their pride.
