Example of a fake painted rust spots on a celadon base?

[Goose_M]

Hello everyone

I'm a newbie here and this is my first post.
Thank you very much for the informative forum that you all have been shared here.
I've learnt a lot.

But It's still quite hard for me to identify age faking porcelain bases
as the fake artists becoming more good at this.

So is this an example of a fake painted rust spots on a celadon base?
