How to display text in wordpress only on site.com/ru/?

Question

CMS

There is one site page site.com/ru/ and you need to put text on it below before the footer and you can’t do this through the admin panel, I just want to insert something like this into the footer:
IF URL PAGE = site.com/ru/ THAN ECHO" here is our text "
How to do it right?
