Нет, не любой.

Olá, Felipe! Pelo que vejo, são realmente muitos russos que pretendem aprender português. No entanto, a maioria de nós não tem muita paciência, ou sei lá o quê, para avançar nisso durante muito tempo :)

Hello, Felipe! Perhaps, some Russians really want to learn Portuguese, but unfortunately, this language is not so popular as English, and less popular than even Spanish. Try to seek a partner via the community section "Find language partner". There is a filter there to help, so you can find Russian people who learn Portuguese and write them. Good luck to you!
