During the Three Kingdoms period, the world was in chaos and fell apart, so there were many well-educated people, who were full of learning, and these full-fledged people assisted their lords in plotting to win the world, achieve hegemony, and save Cangsheng, among which there was a counselor named Jia Xu, whose talent may be above Zhuge Liang and Sima Yi.
Dedication to Zhang embroidery
In the third year of Jian'an, Cao Cao marched south to Zhang Xiu and besieged Zhang Xiu's base area of Yongcheng, but soon after, Yuan Shao took advantage of the false intention to attack Xu Du, so Cao Cao decided to retreat to the rescue, at this time Zhang Xiu and Liu Biao attacked Cao Jun, the result was defeated by Cao Jun, Cao Jun continued to retreat after the victory, so Zhang Xiu saw the opportunity and continued to send troops to pursue Cao Jun, but Jia Xiu said to Zhang Xiu: "You can't pursue, otherwise you will lose" But Zhang Xiu did not listen, or ordered a pursuit, and as a result, Cao Cao personally broke off, defeated Zhang Xiu's army, Jia Xue saw the situation, so he said to Zhang Xiu: "Hurry up and pursue." Zhang Xiu said, "I didn't listen to your advice just now, so I failed, why do you still want to hunt down and kill Cao Jun now?" Jia Xu then said: "Now the situation is different, hurry up and pursue, we will definitely be able to win", so Zhang Xiu followed Jia Xu's advice to continue to pursue and kill, and the result was a big defeat of the Cao army, which destroyed the rear guard troops of the Cao army.
Afterwards, Zhang Xiu asked Jia Xu why, and Jia Xiu said to Zhang Xiu: "When the Cao army first began to retreat, Cao Cao personally broke the rear, so the soldiers were strong and brave, so it was difficult for you to win, but cao jun just won, he immediately retreated, indicating that something happened in his rear, this time it was a real retreat, at this time the general who left the broken one must not be as good as the general, so it will definitely fail", Zhang Xiu listened to it and deeply admired Jia Xu.
Later, Yuan Shao wanted to surrender Zhang Xiu, and Zhang Xiu also wanted to surrender yuan Shao, but was opposed by Jia Xu, who said to Zhang Xiu: "Yuan Shao's temperament is small and cannot tolerate people, if he surrenders to Yuan Shao, the consequences will not be very good, but if he surrenders to Cao Cao, he will definitely get courtesy, because Cao Cao has great ambitions and will certainly ignore the previous suspicions", and later Zhang Xiu listened to Jia Xu's advice, surrendered to Cao Cao, and was reused by Cao Cao, and Jia Xu also became Cao Cao's adviser from then on.
Dedication to Cao Cao
In the Battle of Guandu, Cao's army ran out of grain and grass, and it was difficult to defeat Yuan Shao for a while, so Cao Cao asked Jia Xu, and Jia Xu said to Cao Cao: "Your ability is above Yuan Shao, the reason why you can't win is because you think too carefully, as long as you seize the opportunity, you will definitely be able to defeat Yuan Shao", and later Xu You came to vote, Cao Cao seized the opportunity, sent troops to attack Wuchao, and burned the grain and grass of Yuan's army in one fell swoop, and Yuan Jun's army was immediately defeated.
In the Battle of Weinan, Han Sui and Ma Chao led an army of 100,000 to resist the Cao army. Cao Cao then asked Jia Xu how to break the enemy, and Jia Xu replied: "It can be solved with a divisive meter!" So he wrote a book to alienate Ma Chao and Han Sui, causing them to be in civil unrest, and Cao Cao immediately led an army to attack and destroy the combined forces of Han and Ma.
Dedication to Cao Pi
At that time, Cao Cao was old and had never been crown prince, and Cao Pi knew that his talent was inferior to Cao Zhi's, so he asked Ji Jia Xu, and Cao Pi asked Jia Xu: "What should I do?" So Jia Xu said: "As long as the general does not violate filial piety, works diligently and sincerely, is frank and frank, cultivates morality, and cultivates temperament", so Cao Pi did as Jia Xu said, and was soon made crown prince.
Later, Cao Pi established himself on behalf of Han and established the State of Wei, but the first conquest of Eastern Wu failed, so he asked Ji Jia Xu: "I want to unify the world, the State of Shu and the State of Wu, which one will I attack first?" So Jia Xu said: "We should first govern the country well, and then send troops not too late", Cao Pi did not listen, continued to cut down Wu, and the result was fruitless.
From the above examples, we can see Jia Xu's talent, he is the real exhaustive strategy, every time the plan can work, which shows Jia Xu's superiority.
