Lviv in particular, and that region of western Ukraine in general, has a unique history within Ukraine. It was it was part of the Austro-Hungarian Empire up until the first world war. Then it became part of Poland, after a war between Poland and Ukraine, and western people's Republic and then for a long time it was up until the second world war it was part of Poland. And it was acquired by the Soviet Union and added to Ukraine.  So it has a different history than the rest of Ukraine and a distinct culture, so the influence of russification and everything was less in that region and there's more polish influence in that region then then another areas in Ukraine. And you can feel that if you walk around the buildings, you can see Polish inscriptions, in the churches you can see Polish monuments and statues to people there.  There's a lot less spoken Russian in Lviv. It's not if it's not say that Russian is absent but it's a lot less well spoken and in Lviv in particular are people who do not know Russian, so that's in contrast to the rest of Ukraine where someone may prefer to speak one language or the other, but they generally have an understanding of the other that they don't speak. In Lviv that may not be the case. You may run across people who can't speak Russian.
