“meat floss” is a thing. look it up real quick. is probably a bun of some kind filled with chicken based meat floss. i don’t think there’s been any translation error. just a somewhat obscure food in the West. it’s tiktok (or whatever equivalent) famous in China and other Asian countries

edit: pretty sure this is the exact product with pictures. . yep, that’s a bun with meat floss in it. the op picture intentionally doesn’t show the front of the box to make it seem mysterious.

google a “porksung bun” not the same, but I’ve seen these in the supermarket, floss is the english word for it so they are very similar.
