Newbie question for white hat seo

Hello everyone (my first thread here, very happy to join the world of SEO)

Here is my question:

I have a website that it is in Bulgarian and my target audience and clients are also Bulgarian. I have some powerful urls (high domain rate and Page Quality Score 80+) on which I can share my website's backlinks. However, these powerful urls are in English and have nothing to do with my services. For example, my website is about language courses and the powerful URls I have are about Design and IT. Would it make sense to connect my website to these powerful backlinks if my audience is non-english speaking and services are totally different? Would it harm my SEO rankings in the long-term or will it help to get higher rankings on Google for my target audiences? It could be a silly question but thank you all for reading!

In my opinion if you get backlinks from another country for you "shop" was for nothing ... i try this thinks doesnt work for me , maybe somebody know much better and tell us one solutions.

It works amazing for me.

As for me, there is no reason to do it, but anyway good luck!
