He felt sad that there's no generation that experienced meeting bears. He felt sad that our culture was disappearing. So he restored it. Here's an example of that lost culture.

The "Ukeung culture" where people made "ooooh" sounds so animals would avoid them ahead of time. Director Moon emphasized the need for a culture of mutual consideration between animals and humans to enable coexistence. He said, "In areas where animals and humans inevitably overlap, individuals must improve their awareness so they can each maintain their territory." "You've never seen a rabbit when you go to the mountains, right? Never saw a roe deer? Have you been to Jeju Island? Did you see roe deer there? When we think of Jeju, we think of roe deer. Halla roe deer. The problem with our mountains is that you can't see animals when you go there. It's unfortunate." He said, "A truly living nature is when you can see roe deer, Korean musk deer, and wild boars in the mountains." Then he raised his voice: "Our nature right now is just 'reforested,' but we can't call it a healthy ecosystem." He also pointed out changes in people's lifestyle habits. In the past, there was a culture called 'Ukeung culture' where adults climbing mountains would make 'ooooh' sounds or create vibrations with their walking sticks—'bang bang'—to make animals avoid them. But that doesn't happen anymore.

Our Ukeung culture where we desperately shouted and banged the ground with walking sticks out of fear of being attacked while hiking has disappeared, which is sad. And so he says it would be nice if you went into the mountains and saw rabbits, roe deer, wild boars, and even bears—but they're gone, which is unfortunate.

You

Why are you doing this kind of shit?

Why...? Well, because...

It's... fun.

'Cause it's entertaining watching humans get eaten by monsters, that's what I'm saying.

Of course, there are some bastards who wouldn't want to see that kind of thing.
