First of all, 450,000 Zhao troops were wiped out before and after the battle of Changping, which fundamentally weakened Zhao, the strongest opponent among the six Kanto countries at that time, and also gave great shock to other Kanto governors. Because Qin won the whole war, the situation that it dominated the whole country became irreversible, and it took a sharp turn from now on. After the Battle of Changping, the State of Qin launched the Battle of Handan. Although Handan, the capital of Zhao, was not breached, the war still caused heavy casualties to Zhao. In this case, Yan sent two armies and two thousand chariots, and ordered Li Fu to lead an army to attack Juancheng. Facing the Yanjun, the prince of Zhao sent Lian Po to lead the troops to fight back, defeated Yanjun in Juancheng, killed Li Fu, and captured Qing Qin and Lexian alive.
On this basis, Lian Po led the Zhao army and surrounded the capital of Yan. Yan gave up five cities for peace, and Zhao promised a truce. After World War I, the prince of Zhao named Wei Wen Lian Po and Xin Pingjun, confusing the real with the fake. In this regard, the author believes that although Zhao was seriously injured in the battle of Changping and the battle of Han, after riding and shooting, his combat effectiveness in the army is still far better than that of Yan State. In addition, although the Zhao army was defeated, its combat level was undoubtedly the highest among the seven heroes of the Warring States. In the long battle with Zhao, Zhao's ability has also been improved. Although it is not as good as the current Yan army in number, it can beat back the Yan army's attack because of its leading combat effectiveness.
On the other hand, Zhao's army has the future command of Lian Po, and the generals of the Yan army are no longer as famous as that. As far as Lian Po is concerned, it is also called "the four great names of the Warring States" with Tian Lei, Wang Jian and Li Mu. In the thirty-second year of Zhou Nanwang's reign, he led an army to attack Qi, won a great victory, captured the yangjin Dynasty, and became a minister. He is famous as a general because of his courage and great achievements. At the beginning of the long war, Lian Po held his ground and successfully resisted Qin Jun's attack. After being replaced by Zhao Kuo, the battle of Changping was defeated. Therefore, for Lian Po, he can be compared with Tian Lei, Wang Jian and Li Mu. On this basis, Zhao's general level and soldiers' fighting capacity are obviously higher than that of Yan's army, which is the key for Zhao's army to win more with fewer troops.
Finally, for Zhao, in the Han War after the Battle of Changping, he was repelled because of his unity, that is, strong cohesion. This not only inspired the morale of Zhao soldiers, but also made them more United. In addition, Guo Yan's fish in troubled waters with Zhao naturally allied Zhao's soldiers with the enemy. Chapter 69: "The disaster is greater than underestimating the enemy, and underestimating the enemy has lost my treasure several times. Therefore, if we unite to resist, the mourners will win. " In the face of the Yan army's attack, Zhao's soldiers were "sure to win", while the Yan army underestimated the enemy. Of course, due to the restraint of Qin, Zhao led by Lian Po finally agreed to the peace of Yan, and did not further destroy Yan. In addition, in 243 BC, Zhao sent Li Mu to attack Yan State and captured Wusui and Fangcheng. Zhao gradually recovered and attacked Yan many times, which led to many wars and Germany.
