How to set up a redirect in wordpress from a domain to a subsection of the site depending on the user's location?

Question

Domain name market

Those. it is necessary that from the site.ru site for Russian-speakers redirect to site.ru/ru, and for others to site.ru/en (set up these subsections through the multisite function on wordpress)

Answer 1

on site.ru/ru, and for others on site.ru/en

What about site.ru?
It is necessary to ask what language you speak to determine the language of the browser and redirect.
PS. And I would use not a network, but multilingual plugins - everything would be simple.
