In the Battle of Changjin Lake that once changed the world structure, the Chinese wore thin clothes, carried crude weapons, and were hungry. They charged endlessly in the severe cold of 30 to 40 degrees below zero. In this harsh environment that almost exceeded the limits of human survival. Under such circumstances, the war between the Ninth Corps of the Chinese People's Volunteer Army and the First Marine Division of the U. S. Marine Corps, an elite unit of China and the United States, with vastly different weapons and equipment, seems to have gone beyond the scope of a conventional war and is more like a desperate contest of willpower.
