The significance of the Changping War.

The Battle of Changping was from 1953 to 1955 (April to September of the lunar calendar, from the beginning of the 54th to the beginning of the lunar calendar from April to September, and from the beginning of the 54th to the 55th of the Zhou Bao Wang). The famous Qin general Bai Qi led an army to fight the Zhao army at Changping (長平, in present-day Jincheng, Shanxi Province), northwest of Gaoping. The Zhao army was eventually defeated, and the Qin army won the battle to occupy Changping, killing 200,000 soldiers of the Zhao state.

This war was a strategic decisive battle between Qin and Zhao. In the war, under the guidance of the war, the King of Zhao was ignorant of the basic situation of Qin Qiang and Zhao Weak, eager for victory, and mistakenly adhered to the offensive strategy. The State of Qin abandoned lianpo's famous generals, while Zhao Kuo replaced lianpo; Zhao Kuo followed the intentions of king Zhao, eager for victory, changed Lianpo's defensive arrangements and military rules, changed officials, and organized an attack. In response to Zhao Kuo's weakness of being proud of the enemy, Bai Qi took the option of pretending to be defeated, luring the enemy out of the position, and then dividing the encirclement, annihilating the operational policy, and winning the war. Zhao Guo was wounded in World War I, speeding up the process of unifying China with the Qin state. This war was the earliest, largest and most thorough war in ancient Chinese military history.
