The state of Qin attacked South Korea, and the troops were stationed in the country. Zhao Wang summoned Lian Po to ask: "Can you save South Korea?" Lian Po replied: "The road is dangerous and difficult to rescue." Zhao Wang called Le Cheng again and asked what to do about it. Le Cheng's answer is like Lian Po's words. Calling Zhao She for advice, Zhao She replied: "This road is long and dangerous, just like two mice fighting in a hole, which will be the victory of the brave." The Prince of Zhao appointed Zhao She as a general to help the South Koreans.
Thirty miles after the army left Handan, Zhao She ordered in the army: "Anyone who persuades with military matters will be put to death." Qin Jun marched into the west of Wu 'an, Qin Jun beat drums and shouted to lead the army to attack, and Wu 'an's roof tiles were all shaken by the shouting. A military officer said to rescue Wu 'an quickly, and Zhao She immediately killed him. Zhao Jun persisted, stayed for 28 days, and strengthened the fortifications. Qin Jun's spies sneaked in, and Zhao She treated him well and sent him away. Qin Jun's spies went back to report to General Qin Jun, and General Qin Jun was very happy to say, "I left the capital for three miles, but I didn't leave, and I strengthened my fortifications. It's not Zhao's anymore." Zhao She had already sent away the spies in Qin Jun, so he went to camp and followed. He arrived in two days and one night, and ordered the sergeant who was good at archery to camp at a distance of five miles. As soon as he had set up camp, Qin Jun heard about it and came between people. Sergeant Xu Li asked Zhao She for instructions on military issues. Zhao She said, "All right." Xu Li said, "Qin Jun didn't expect the Zhao army to come here. Their attack momentum must be very strong. General, you must be ready. If you don't, you will fail. " Zhao She said, "Please accept the order." Xu Li said, "(If defeated) I would rather accept the axe-like criminal law." Zhao She said: "Waiting for you to be the magistrate of Handan County after the war." Xu Li also advised: "The army that occupied Beishan first won, and the later party will fail." Zhao She agreed, and immediately sent ten thousand people to occupy Beishan. Qin Jun was sure enough, but the attack could not be won all the time. Zhao She led the attack and defeated Qin Jun. Qin Jun was defeated and fled, so he lifted the siege and returned home victorious.
