From the state to Florida, we're now taking you to the nation of South Korea where the 2018 Olympic Winter Games are wrapping up their first week.

After this weekend, the luge and skeleton events will be behind us. More skiing, bobsledding, skating and snowboarding are still ahead.

And here's where the medal count stood as of Thursday night, before Friday's results came in. Norway led the pack with 17 overall medals. Germany, Canada, the Netherlands and the U.S. rounded up the top five countries for medals won. Of course, by the time you see, there could have been some changes to these counts.

You might have heard some of the competitors described as Olympic athletes from Russia. Though they have won five medals as of last night, their national anthem was not played and they're not allowed to compete under the Russian flag. These are some of the International Olympic Committee's penalties on Russia following its massive doping scandal, but the athletes from Russia aren't the only ones competing under unfamiliar circumstances.

WILL RIPLEY, CNN INTERNATIONAL CORRESPONDENT: Hey, I'm Will Ripley at the 2018 Winter Olympics. Less than 200 miles separates Pyeongchang, South Korea, from Pyongyang, North Korea. But in many ways, the two places are worlds apart. And for the North Koreans visiting here, they're seeing a lot of things for the first time.

The North Koreans arrived here in Pyeongchang on this high speed train, the KTX. Built in 2004, it travels almost 190 miles an hour. They don't have trains like this up North. They're a lot older and a lot slower.

A lot of North Koreans are carrying smartphones these days, at least those privileged enough to live in Pyongyang. But what most don't have is access to the Internet, or search engines like Google. Instead, they have a state-controlled intranet, all the content monitored and censored.

This is probably the first time the North Koreans are seeing these many foreign faces. North Korea prides itself on being racially pure, homogenous. You rarely see these many foreigners in one place.

The North Koreans are also probably hearing this kind of music for the first time. In North Korea, music like everything else, is tightly controlled. Not here.

A lot of these artwork probably looks a little strange to the North Koreans. After all, in Pyongyang, all of the monuments are to the late leaders or the ruling workers party. They definitely don't have stuff like this.

We're about to enjoy a meal that most people in North Korea can't afford. This is Korean barbecue, one of my favorites. And you can't find it up North. For most people, beef, chicken, pork, it's just an unaffordable luxury.

This is our waiter, Chi Yang-sa (ph). He's 21 years old and we were just noticing his blue hair here because in North Korea, you never see this. People only have one hair color. It's the natural dark black or brown.

Something else most North Koreans have probably never seen before, a street light this, lined with stores and neon lights. South Korea is a thriving capitalist country. North Korea, a socialist country. Two neighbors with two very different ways of life.
