Big brother, look! There are so many people up ahead wearing the same clothes and shouting slogans while they walk!

That's a 'power-walking group.' They walk together for exercise.

Why do the cars keep honking?

Because they're walking in the traffic lane, so the cars can't get through.

Then why don't they walk in the park?

Exactly. The park is right next to them. I saw on the news that the country is going to revise the traffic law, and in the future people won't be allowed to occupy roads for activities like this.

What will happen after the law changes?

If the police see them, they'll come and tell them to move to a park or sports field. Cars use the road, and people use the sidewalk.

I understand. Big brother, let's go home quickly. I'm a little scared.

Okay. Hold my hand. We'll walk on the sidewalk. Don't be afraid.
