"it's more like people just don't know what it is"

Can a highly traditional and orderly society like South Korea's develop a thriving graffitti / street art culture?  Maybe!  To wit:

"'Honestly, graffiti is just as much of a part of subculture in Korea as it is in other countries, and there are people who don’t like it in other countries too,' said Jay Flow. 'But in Korea, it’s more like people just don’t know what it is. We’re not welcome, and it’s hard. I keep doing it to make an appeal to Korean society, as if we’re having a go at people.'

Jay Flow started spray painting on walls in 2001, when graffiti was not well known in Korea, while Royyal Dog rose to stardom in the United States in 2016 and is known for adding a unique Korean touch to his works. The two close friends collaborated on the main piece of this exhibition, a mural of singer Billie Eilish and Jay Flow’s signature shark humans."

I mean, if you've got Billie Eilish in your corner you're off to a good start.
