How is the content template on the right side of the ecshop user center implemented?

As shown in the picture, I only know that it is displayed through language packs. I don’t know how to implement it. I just used ecshop and I don’t know many things? I hope someone can explain this to me? (PS: Don’t ask why you still use ecshop)
