This is a true story that happened during the War of Resistance Against Japan and the War of Liberation. Chiang Kai-shek of the Kuomintang prevented our field troops from going north to the front line of the Huaihai Campaign and launched a desperate battle at Yaxiahe. Our underground party members were seriously injured during the battle and lost contact with the main force. The story is twists and turns and touching. Let us witness this history together.
