A video that went viral on Tuesday shows 10 women in pink cheongsam dancing in two lines to Chinese music at Seongsan Ilchulbong, Korea Joongang Daily reported.
In front of them are a man wearing a hat and sunglasses and another man holding a red event banner that reads Art Troupe.
Some users criticized the scene.
One netizen wrote, "Playing loud music and dancing at tourist sites is a nuisance," and, "Why are they behaving like this in another country?" Chosun reported.
Others defended the group, saying, "It’s similar to performing Taekwondo abroad," "Group dancing is a trend among tourists in China," and, "It just looks like they're filming something."
