How to make a second language inside a directory?

Question

WordPress

Hello, I ran into a problem when creating a second language for the site. I was able to translate everywhere, but inside the catalog in the product I can’t. Can you please explain in which files this can be done or how to create a second directory then.

You can check the site at the link https://tractor.uz/osma_uskunalar/tractor-uz-till

Everywhere changes, but neither the footer nor the header changes.

You can go to osma uskunalar there as you see the normal uzb
