This episode mainly introduces the blatant use of bacterial weapons by the United States to reverse the defeat, and the little-known historical facts of the Volunteer Army and the people of China and North Korea jointly resisting the germ warfare of the United States. In 1952, in order to break the deadlock on the Korean battlefield, the U.S. military flagrantly violated international conventions and used bacterial weapons to attack Chinese and North Korean troops and innocent people. For this reason, under the leadership of the Central Committee of the Communist Party of China and the Volunteer Army Headquarters, the officers and soldiers of the Volunteer Army and the Chinese and Korean people launched a vigorous anti-bacterial warfare campaign. This campaign exposed the brutal face of the United States and guaranteed the final victory of the war.
