Ignorance is not a shield against controversy. The 15th was Liberation Day, which marks the 78th anniversary of Liberation Day. August 15 marks the liberation of the Korean people from the Japanese colonial rule in 1945 and celebrates the establishment of the South Korean government. Actress Song Hye-kyo, along with Professor Seo Kyung-duk of Sungshin Women's University, donated 10,000 copies of a guide to inform the Korean Studies Center of Hawaii State University in the United States. On the other hand, there are some controversial stars who traveled to Japan on Liberation Day or praised Japanese culture. Actor Ko So-young posted several photos on Jasin's SNS with " ⁇ " on the 13th. In the photo, Ko So-young and Jang Dong-gun boarded the plane to travel to Japan. On the 15th, they showed their family enjoying a trip to Japan. Especially in the public photos, there was a picture of Ko So-young posing in front of Japanese animated characters. I also uploaded pictures of shopping at famous Japanese grocery stores and pictures posing in the background of Japanese menus. As the criticism continued, Ko So-young said, "I am sorry for the inconvenience on the important day. I deleted Baro after I knew it, but it was too late, "he said." I will be a little more careful in the future. " Ko So-young and Jang Dong-gun are South Korea's leading actors, and Ko So-young is an influencer with 320,000 followers. This is not the first time that celebrities have been ignorant of history. "Exo Chanyeol uploaded Japanese singer Yonezu Kenshi's lemon on Liberation Day three years ago and uploaded it to Jasin's sound cloud. As the criticism of the netizens continued, Chanyeol deleted the sound source Baro. Girls' Generation Tiffany Young has also been controversial in the past, using stickers with emoticons and Wook on the eve of Liberation Day. At the time, Tiffany Young finished the SM Town concert at the Tokyo Dome in Japan and uploaded pictures of Girls' Generation members glass and swimming, and put emoticons. It was not strange that the Japanese flag was put in order to certify the Japanese performance, but there was a public opinion that it was careless in time, and a picture with a sticker of "Tokyo Japan" containing Wook was added to fuel the controversy. They should be more careful and careful about every single word Jasin utters, especially when it comes to Korean history, which has high public interest. In many ways, it's a line that doesn't suit a top star.
