The Phong Nhat - Phong Nhi massacre (Dien Ban district - Quang Nam province) on February 12, 1968 recounted by Korean journalist Koh Kyoung Tae in a responsible manner was truly surprising and shocking! From the perspective of Korean soldiers engaged in war and victims witnessing the massacre, Phong Nhat and Phong Nhi's wounds not only belonged to innocent Vietnamese civilians, but were also etched into the conscience of Korean veterans who were pushed into a blind and brutal campaign. The book is like a new, thrilling and impressive war documentary. The author of the book was the Editor-in-chief of "Hankyoreh 21". This newspaper advocates to reflect on the history of Korean fighting in the Vietnam War with the message "Sincerely apologize to Vietnam".
