Mystery bowl I've had for years - Qianlong ware, China

Sorry if the photos are a little dark. I've had this bowl for many years but I've never been able to figure out the mark. Style looks like it could be eastern? The mark could depict a number of different letters or symbols. Anyone recognize this?

Thanks for the lead! I didn't consider it could be that old.

I wish I could learn more about eastern pottery but I find it extra challenging not having a grasp of the language and letter characters. And then on top of that deciphering the real ones from the replicas and fakes. I have a few Sothebys and Christies catalogs for eastern events I saved because they can be so beautiful to look through.
