Hallyu star Monsta X and Professor Seo Kyung-deok of Sungshin Women's University, who have spread Korean around the world, joined forces to unveil the holiday greeting of the "Easy Korean, Right Korean" video campaign on the 10th.

The seven-minute video, produced by the Ministry of Culture, Sports and Tourism and the Federation of Korean Language and Culture Center, dealt with words in a quiz format that should be taken care of when greeting family and relatives ahead of the holiday.

Professor Seo, who organized the video, said, "There are many words that are easy to miswrite in everyday life, but I made the video with the intention of using such confusing expressions properly," adding, "I wanted to spread the timely, easy, and correct Korean expressions to netizens through the video."

MONSTA X said, "We are glad to participate in this meaningful video production, and I want to help the spread of easy and correct Korean language at home and abroad."
