China did not care about their troops' lives. Their bodies were in fact the weapon. That's the main reason there were heavy casualties on Chinese side no matter what they achieved throughout the war. Concentration of troops on the UN forces' weak point paid off and the tactic was successful. However, at Jipyeong-ri, it finally failed. Chinese command mistakely assumed the tactic still effective and UN forces would withdraw like before. Instead, the US command prepared to hold on the positions with enforced arms and plans. There also were troops from France, UK and Korea Republic. Let's be clear: The Red China, North Korea and Soviet were NOT the defender againt U.S. but they invaded the world of freedom and democracy with the agreements each other before the war. That's why UN forces with 21 nations responded. You China, DO NOT SAY AGAIN - "THE KOREAN WAR was DEFENDING AGAINST UNITED STATES" any more. Thet's a total lie. You were the invader.
