70 years ago, 2.9 million volunteer soldiers went to the Korean battlefield to fight the invaders side by side with the Korean soldiers and civilians. With the courage not to be afraid of sacrifice and the courage to go through fire and water, they carried out thrilling struggles on the Korean battlefield again and again, and staged scenes of mighty and majestic living dramas. With their blood and life, loyalty and responsibility, they have created a group of heroes that are epic, courageous, and shine in the annals of history. They are worthy of the title of "the cutest people".
