One of the Chinese word for red panda is literally Firefox, 火狐, that’s where the web browsers name comes from.

I think Pop OS is a great place to start. I haven’t personally used it but Linux Mint is commonly recommended to people who have only used windows before, it tries to have a similar UI experience.

Linux can do most things windows can, except it’s free. The best thing about Linux is the depositories, unlike windows you rarely download apps from the Internet, instead you can download them from a repository. In Pop OS it’s called Pop shop, it’s different depending on which OS you are using.
