Jia Xu (1April-August 1 1, 223) was a native of Liangzhou Ancient Collection (now Liangzhou District, Wuwei City, Gansu Province). From the end of the Eastern Han Dynasty to the beginning of the Three Kingdoms, famous counselors and military strategists were the founding heroes of Cao Wei. Originally the Ministry of Dong Zhuo, after Dong Zhuo's death, Li Jue and Guo Si counterattacked Chang 'an. After Li Jue and others failed, they became Zhang Xiu's advisers. Zhang Xiu defeated Cao Cao twice with his stratagem. Before the battle of Guandu, he advised Zhang Xiu to surrender to Cao Cao.

When he was young, his reputation was not outstanding, but he was highly praised by Hanyang celebrity Zhong Yan. Later, he became a subordinate of Dong Zhuo and worked as a captain in Peiping, Tianjin and Tianjin. Later, he was promoted to a captain because of soliciting guests, and he was under Niu Fu's account. After the demise of Dong Zhuo, Niu Fu also died, and Wang Yun liquidated Dong Zhuo's remaining party. Li Jue listened to Jia Xu and attacked Chang 'an with Guo Si, Category and Zhang Ji. Lyu3 bu4 was also a Shoujiang and fled to Kanto.

In order to avoid this disaster, Emperor Xian of Han led his ministers and guards to flee to Luoyang. Jia Xu once denounced the disaster brought to the people by the war with Guo Si, so Jia Xu alienated the hired Qiang-Hu mercenaries, let them leave, helped Emperor Xiandi leave Chang 'an, and protected the ministers persecuted by Guo Si.

After the emperor asked to return to Luoyang, he was escorted by Duan Wei and others. Because Duan Wei and Jia Xu are in the same county, Jia Xu abandoned Li Jue and followed Duan Wei. Jia Xu met privately with Zhang Xiu, and Jia Xu repeatedly proposed his coup to help Zhang Xiu resist Cao Cao. Cao Cao's general Dian Wei, his eldest son Cao Ang and his nephew Cao Anmin died in battle. It was suggested that Zhang Xiu make peace with Liu Biao, but Cao Cao was defeated many times, so that Cao Cao could not attack Wancheng.

In 200 AD, Cao Cao and Yuan Shao fought in Guandu. After that, Cao Jun's rations will run out. Cao Cao asked Jia Xu for advice, Jia Xu offered advice, and Cao Cao said yes. Then Xu You gave advice to Cao Cao, who attacked Yuan Shaowu's lair granary and broke it, leading to Yuan Shaowu's rout. After Cao Cao's victory, Jia Xu was named Doctor Taizhong.

In the twenty-second year of Jian 'an (2 17), Cao Cao did not establish a prince, Cao Pi was a general with five senses, and Cao Zhi was a famous soldier Fang Sheng when he died. Cao Pi sent someone to Jia Xu for advice. Jia Xu said, "I hope the general can carry forward morality, cultivate tolerance, practice the responsibilities and obligations of scholars, be diligent and tireless, and do nothing that violates filial piety." Cao Pi listened to his advice and deliberately honed himself. Later, Cao Cao privately asked Jia Xu what he thought of the heir, but Jia Xu kept silent. When Cao Cao asked him why he didn't answer, Jia Xu said, "I was thinking about Yuan Shao and Liu Biao." Cao Cao laughed and made xelloss a prince.

Jia Xu thought he was not an old minister of Cao Cao, but he was resourceful and afraid of Cao Cao's suspicion, so he adopted a self-protection strategy, kept himself indoors and kept away from people in private. His children didn't take power after they got married. At that time, all the people in the world spoke highly of the wise man.

What was the final outcome of Jia Xu?

In the 22nd year of Jian 'an (2 17), Cao Pi was appointed as the heir.

In the first year of Huang Chu (220), Cao Pi acceded to the throne. In order to repay Jia Xu's kindness, he worshipped Jia Xu as Qiu, joined Wei Shouhou, and increased the grain market by 300 households, with a total of 800 households. He also divided the food city into two hundred, named the youngest son as Liehou, and appointed the eldest son as a captain Xu.

In March of the fourth year of Huang Chu (223), Cao Pi first conquered Wu Dong, but failed to achieve the expected results. At the beginning, Cao Pi asked Yu Jiaxu, "I want to unify the world. Which should Wu and Shu conquer first? " Jia Xu suggested governing the country before using force, but xelloss didn't listen. He really failed. In June of the same year, Shen Jiari (1 1 August), Jia Xu died at the age of 77. He was born in Suhou, posthumous title, and his eldest son is Jia Mu.

Many years later, Jia Xu shared Wei Wendi Temple with Wang Lang, Cao Zhen and Xin Pi.
