A dance called "kemusan" or "Subject Three" has gone viral on social media. The dance is said to have been performed first in 2021 at a wedding in China's Guangxi Zhuang autonomous region.

Guangxi in South China is renowned for its stunning landscapes and vibrant performing arts. It is said that people from Guangxi undergo three tests in their lifetime: singing folk songs, eating rice noodles, and dancing. It's from these activities that the term "Subject Three" originated. The dance has become popular on social media due to its catchy moves, set to a remixed version of the song "A Smile in the Martial World."
