In Russia, you can say "Как дела?" (Kak dela?) to ask someone "What's up?" or "How are you?". This is a common way to greet someone and inquire about their well-being in casual conversations.
You can also say "Что нового?" (Chto novovo?) to ask "What's new?" or "What's happening?" in a similar way.
It's worth noting that Russians often greet each other with a kiss on the cheek, especially among friends and family. This is a common cultural practice in Russia and is seen as a friendly gesture.
