What brand is the most expensive pen in China?

Made in China? Let's be a hero (or there are no other high-end brands except heroes, and things like longevity have all closed down. Picasso, a fake thing, doesn't participate in the discussion)

In foreign countries, Parker Videvin, the most expensive pen, can stand aside. The most expensive is a large class series of Montblanc, which is full of diamonds. There is also an aurora, the name of which is forgotten, which is much more expensive than Montblanc.
