How Do You Play? (놀면 뭐하니?)

(It's early in the morning, and the center of Seoul...)

- Hello. - So early in the day...

Hello.

What... What are we doing?

It's Gyeongbokgung Station.

- Don't they rent hanbok here? - What's this?

- Is this a fortune-telling shop? - Is this it?

They rent hanbok here.

- Why are we renting hanbok? - What's this?

It's a hanbok rental place.

- Hello. - Are we going out in hanbok today?

- Comfort... - Hello.

Hello.

(The members are welcomed by many colorful outfits.)

- Hello. - Do we pick something?

Look around for what you'd like.

- Us? - We pick?

- How do we know... - We don't know what it's for.

The sizes are...

Is there... It's right here.

Hey, that's pretty.

Why does this make me want to cry?

- Why? - I don't know.

- Your previous life... - It must be my other life.

Were you a clothesmaker?

There's no way you were...

You don't look like someone who'd live in a palace.

I feel emotional.

Which hanbok should I...

We picked out some outfits. You can change into them.

It's not on this rack?

- It's not here? - What...

- Your pick... - We were told to choose.

Where are they?

These ones?

These are...

This look is...

I haven't worn a bamboo cap in a while.

- The last time was... - "Bamboo, bamboo."

This is a first for me.

Is it really?

- Hey, you... - Was that a dance challenge?

- Yes, okay. Haha... - You tried.

He acted like that until his early 40s.

The last-ditch effort to be young.

- It's his last chance. - "Last..."

That's why people laugh.

Why did you tell us to dress like this?

Tomorrow is the 629th birthday of Sejong the Great.

Is it really?

It's Teachers' Day too.

Yes, they chose his birthday to celebrate teachers.

You'll do things related to King Sejong's achievements.

- You'll split into two... - I see.

You can partner up as you like.

I don't mind...

He gets separation anxiety when I'm not around.

It's serious.

He has separation anxiety.

I don't mind who I partner with.

- Sure. - Of course.

- We're connected. - Yes.

We're both from KBS.

- Let's make it on MBC. - For today...

- Jae Seok and Kyeong Hwan. - We leave now?

Go to Gyeongbokgung Palace.

- We go to Gyeongbokgung Palace? - Yes.

At this hour? They won't be open yet.

- Gyeongbokgung Palace? - You must welcome visitors.

- Like this? - Looking like this?

No? Do you pose for photos?

- We go now? - Let's go.

- Okay, then... - That's it?

Okay. See you.

Hey, Kyeong Hwan.

Visiting Gyeongbokgung Palace at this time of day...

FYI, I've never been inside Gyeongbokgung Palace.

You what?

I might as well be a visitor.

You've never been inside?

No. I never had the chance.

That makes zero sense!

I meant to visit, and even my parents wanted to,

so I said I'd take them and still...

These days, so many people visit,

- so it's not that easy. - I know.

- It's tough. - It's an ordeal.

It's always crowded.

- Gosh. - Goodness.

I've never walked along this street either.

- You haven't? - No.

- Many people jog here. - It's nice.

- It's allowed? - Yes.

It must feel nice to jog or walk...

along this street.

To think that I've never been here.

How did you never visit Gyeongbokgung Palace?

- Hello. - Oh, hello.

- Nice one. - Unbalance!

- They're a running crew. - Yes.

- They take photos as they jog. - Yes.

Oh, this is great.

- My goodness, Kyeong Hwan. - Yes.

- Oh, my. - Seriously. Gyeongbokgung Palace...

And this is Gwanghwamun.

May I enter?

(It's quiet inside the palace before opening hours.)

I can't believe we get to come inside before the other visitors.

At last! This is my first time being inside Gyeongbokgung Palace.

After becoming a regular member of the show,

- My gosh. - I got to visit the palace.

I genuinely love old palaces.

I used to come here with my friends once in a while.

We'd visit Gyeongbokgung Palace and Changdeokgung Palace.

You know what?

Foreigners look up places to visit and come here.

(The more they explore, the more fascinated they are.)

(They are the only ones in this large palace.)

This is so cool.

But what are we doing here?

My goodness.

- Oh, my. - What's going on?

- He's dressed in hanbok. - Wait. There's a guy.

Who is he?

- His rank is higher than ours. - He is a higher rank than we are.

(Even at a glance, the man exudes a high status.)

Gosh. We're here, but clueless about what we're doing today.

- Hey, why are you always... - Clearly, his rank is higher.

"Gosh. We're here."

This is the Royal Decree from King Sejong.

- Pardon? - Listen up.

"To me, measuring Joseon's land is central..."

"to the administration of the kingdom."

"Today,"

"I will grant you a new invention to carry on..."

"the legacy of girigocha,"

"Joseon's representative distance-measuring chariot."

"Receive the King's command and map out the roads of Hanyang."

Pardon? You want us to map out the roads of Hanyang?

- That's... - Girigocha?

It's a semi-automatic wagon from the Joseon Dynasty...

that tracks distances...

by striking a drum or a gong after traveling regular intervals.

I see. I didn't know people did that back in the day.

(This achievement of King Sejong helped enable precise mapmaking.)

So where do you want us to measure distances?

- He stopped responding like AI. - He...

I guess this is all you know.

What's that?

Is that the distance-measuring device?

- Hello. - That's a girigocha?

- Hello. - What's that?

- We're using it as a girigocha. - What...

Is that from a base station or what?

Oh, I see.

What's this?

- Hello. - Hello.

My name is Cho Hyun Joon.

I'm from NAVER's Map Data Planning Team.

- You're from NAVER. - Yes.

- Here's your task for the day. - Okay.

You will walk around many places...

and gather data while operating this device.

Is this the device for Street View?

- Yes. That's correct. - Street View?

- When you look at the map, - Right.

there's a 3D feature...

- that shows the actual street. - That's right.

- That's the job today, right? - Right.

(A map service that offers a 360° real-photo view of the streets)

We go to places that cars can't go.

I see. So is that what you do?

Yes. That's right.

We also walk around the parks.

So we can offer our service to our users.

- So you carry it with you? - I walk around with this on.

- My goodness, this is heavy. - Oh, my.

- You almost ruined the episode. - I almost ruined the episode.

- You almost ruined it. - My goodness. I'm sorry.

- It's all right. - I've never carried this before.

- It's heavy. - My gosh. It's quite heavy.

(The weight of the new invention is hard to carry.)

- The backpack has other devices. - Okay.

There are seven cameras on it.

I see. There are seven cameras on it?

My footage will be from a low angle. Is that okay?

Actually, I can adjust the level. So you don't need to worry.

It's much bigger than him.

(The technology can make up for his short legs.)

How can we measure the distances?

We stop and capture data after walking 10m.

We can't just freely walk around.

- No, you can't. - I see.

When you take ten steps,

- that would be about 10m. - So let me try.

Then do I need to take 11 steps?

- Let's try it. Walk naturally. - Okay.

- That way, later... - Let me try it.

- Let's try it on flat ground. - On flat ground.

- I'll walk how I usually walk. - Try walking naturally.
