It took three years before and after the battle of Changping (in recent years, it has been said that the previous stalemate lasted for two years and six months, and the later white-hot war lasted for six months). It was the earliest and largest encirclement and suppression war in the history of China. The war between Qin and Zhao, the two countries with the strongest strength to unify China, greatly accelerated the process of Qin's unification of China. It is said that the rape and murder of 100,000 people in Zhao Si was regarded as a turning point in the Warring States Period by later generations. After this war, Shandong vassal states no longer have the strength to fight against Qin Jun, and it is only a matter of time before Qin unified China. From national strategy to specific tactics, military strategists have been discussing its gains and losses until now. The battle of Changping had a far-reaching impact on the historical trend of China, which gave birth to the first feudal centralized empire in China history.

The Battle of Guiling is a famous interception battle in the northwest of South Placanticline. In the fifteenth year of Zhou Xian (354 BC), Wei besieged Handan, the capital of Zhao State, and Zhao State asked Qi for help the following year. The King of Qi ordered Tian Ji and Sun Bin to lead the army to rescue him. Sun Bin thought that Wei attacked Zhao with elite soldiers, and the national situation was empty, so he led his troops to attack the girders of Wei capital (now Kaifeng, Henan). Indeed as expected to lure Pang Wei Juan back to the battle. Sun Bin once again ambushed in Guiling (now Changyuan, Henan Province), defeated Wei Jun and captured Pang Juan alive. In this campaign, Sun Bin evaded reality and attacked what was left, creating the tactic of "encircling Wei to save Zhao", which has become a commonly used military means to lure the enemy into submission for more than 2,000 years.

Battle of Maling: During the Warring States Period in China, the Qi army annihilated Wei Jun's famous ambush in Maling. In the 28th year (34 BC1), Wei Fabing attacked Korea, and Korea asked Qi for help. Qi promised to help to promote Korea's resistance to Wei. However, since the war, Wei and South Korea have not lost their strength, so it is not appropriate to send troops to form an alliance too early. Until the Korean army was defeated in five wars, the situation was critical. Wei Jun was also very tired, so he sent troops to save him. Qi Weiwang took Tian Ji as the general, Tian Ying and Pan Tian as the lieutenant, and Sun Bin as the strategist. He used the tactics of "besieging Wei to save Zhao" (see the Battle of Guiling) and led an army to pounce (now Kaifeng, Henan) to induce Wei Jun to come to the rescue to solve his worries. In this campaign, Sun Bin took advantage of Pang Juan's weakness, created an illusion, induced him to submit, and kept the war active. This war is a famous example of ambushing and annihilating the enemy in the history of China War.
