Jia Xuzi Wenhe, a native of Guzang County, Wuwei County, was born in the first year of Jianhe (147). When he was a teenager, he was unknown, and only Yan Zhong, a native of Hanyang, took a special fancy to him, saying that he was a genius like Zhang Liang and Chen Ping.

Later, Jia Xu was recommended as filial piety and served as a Lang official. Jia Xu resigned from his official position due to illness, returned to the west, and arrived in Huangdi County, where he met the rebellious Di people on the way, and dozens of people who were with him were all caught by the Di people, the situation was very critical at that time, and everyone else was very flustered, only Jia Xu was in danger.

Jia Xu said to them: "I am the grandson of Duke Duan, don't bury me alive, my family will definitely be ransomed with a lot of money." At that time, Taiwei Duan Cheng had been a border guard general for many years in his early years, and he shocked the western territory, so Jia Xu used his name to intimidate the people. The people did not dare to harm him, and swore an oath with him and sent him away, and the rest were killed. And Jia Xu is actually not Duan Cheng's nephew, but he is very flexible, and things like this have happened more than once.

Before and after the Yellow Turban Uprising, Dong Zhuo gradually grew bigger in the Yongliang area, and Jia Xu also became Dong Zhuo's subordinate at this time.

After Dong Zhuo entered Luoyang, he coerced the Son of Heaven and ordered the princes to control the court and control the power. Jia Xu served as the commander of Pingjin as the captain of Taiwei Peng, and was promoted to the captain of the school. At that time, Dong Zhuo's son-in-law, Zhonglang, stationed Niu Fu in Shaanxi County, and Jia Xu served in Niu Fu's army.

In February of the fifth year of Zhongping (188), the White Bo Army led by Guo Tai and others of the Yellow Turban Army broke out again. In October of the following year, the Baibo army advanced to Hedong, with a force of more than 100,000 men. Dong Zhuo ordered his son-in-law Zhonglang to lead Niu Fu to lead the army to suppress it, and the initial battle was unfavorable. But later, the Bai Bo army was still dealt with by Niu Fu's subordinate Li Dao and others, and finally killed Guo Tai and surrendered Yang Feng. Later, Niu Fu sent Li Wei and others to crusade against Zhu Jun of Zhongmu, and after defeating Zhu Jun, he went to Chenliu, Yingchuan and other places to plunder, and the place where the Xiliang army passed was captured and killed.

Jia Xu, as Niu Fu's subordinate, should have also participated in these battles.

In the third year of Chuping (192), Dong Zhuo was killed by Lu Bu and Wang Yun, Niu Fu was soon killed by his cronies, and the other Zhonglang generals of the Xiliang Army were even more dead, and they surrendered, and Li Dao and others who returned from victory had nothing to rely on, and the imperial court did not surrender.

At this time, Jia Xu stood up and said to everyone: "I heard that Chang'an wanted to punish the people of Liangzhou, and the monarchs abandoned the crowd and went alone, that is, a pavilion chief can restrain the monarch." It is better to lead the crowd to the west, where to collect troops, to attack Chang'an, to avenge Dong Gong, fortunately, to serve the country to conquer the world, if not, go ahead. ”

In the future, Jia Xu's words led to Wang Yun being killed, Lu Bu fleeing, Chang'an fell into the hands of the Xiliang army again, and the Son of Heaven was once again controlled by demons, which directly established the title of "poisoner" in Jia Xu's later generations.

Less than a month later, the generals of the Xiliang Army succeeded according to Jia Xu's suggestion, conquered Chang'an, and avenged Dong Taishi.

Therefore, Jia Xu was appointed as Zuo Fengyi, because of his merits, Li Dao and others wanted to make him a marquis, Jia Xu said: "That's just a life-saving measure, what merit!" tried his best to refuse, but refused to accept it. and asked him to be a scholar and a servant, Jia Xu said: "The scholar is the commander of the official, and he is respected by the people of the world, and Jia Xu's name has never had prestige and cannot convince everyone." Even if Jia Xu is dizzy in front of honor and interests, it is not good for the country! Li Dao and others then renamed Jia Xu as Shangshu, in charge of election affairs, and did a lot of auxiliary and beneficial things, Li Dao and others were close to him and fearful.

At that time, the contradictions between Guo Yan, Fan Chou and Li Dao had begun to intensify, and the two sides almost made a move several times, relying on Jia Xu to mediate and reproach them many times, Li Guo and others were quite convinced by Jia Xu's words, and the contradictions did not further intensify, but later due to the increasingly bad environment of the imperial court, the internal contradictions in the Xiliang Army also accumulated to a critical point, and Jia Xu was no longer able to prevent the final outbreak of contradictions.

Li Guo and others killed Wang Yun and expelled Lu Bu, coerced the Son of Heaven and ordered the princes, which once again provoked a backlash from the Kwantung princes. With the support of Xuzhou Thorn Shi Taoqian and others, Zhu Jun was the commander, and Zhu Haojie jointly elected him as the Taishi, and passed it on to the shepherds of various states, inviting them to crusade against Li Dao and welcome the Son of Heaven.

At this time, Jia Xu and Taiwei Zhou Zhong proposed to use the edict of the Son of Heaven to recruit Zhu Jun into the court, and Zhu Jun really entered Beijing, and the crisis was resolved.

After the death of Jia Xu's mother, Jia Xu resigned again and was awarded the title of Guanglu doctor, but soon Li Wei killed Fan Chou and Guo Yan to start a big war in Chang'an, and Li Wei asked Jia Xu to come back as a general of Xuanyi.

Li Wei and Jia Xu discussed wanting to welcome the Son of Heaven to his camp, but Jia Xu thought it was impossible and said to him: "You can't do this, coercing the Son of Heaven is not the great righteousness!" It's a pity that Li Dao didn't listen.

Zhang Xiu knew and said to Jia Xu: "You can't live here for a long time, why don't you leave?" ”

Jia Xu replied: "I am deeply favored by the country, and I can't abandon the righteousness, you can go!" I can't go. ”

At that time, Li Dao summoned thousands of people from Qiang and Hu, first gave them royal supplies, and then promised them the women of the palace, asking them to help attack Guo Yan. These Qiang and Hu came to the place where the Son of Heaven was many times and said loudly, "Is the Son of Heaven inside?" Where are all the palace beauties that General Li promised us? Emperor Han Xian was very distressed, so he summoned Jia Xu. Jia Xu secretly had a dinner with the leaders of Qiang and Hu, promised them knighthoods and heavy treasures, and successfully lured them out of Chang'an. Li Dao's power was also hit as a result.

Later, Jia Xu made great efforts in Li Guo to talk about peace, the Son of Heaven to the east and protect the ministers, and finally achieved the goal, the war in Chang'an gradually subsided, the ministers were protected, and Emperor Xian also decided to go east to Chang'an. After the Son of Heaven left Chang'an, Jia Xu returned the official seal ribbon.

But what people didn't expect was that a lot of things happened on the way to the eastward migration of the Son of Heaven, Guo Yan left the team of the Son of Heaven, and united with Li Dao again to recapture the Son of Heaven, the army guarding the Son of Heaven was defeated, many ministers were captured by Li Guo's army, Li Wei didn't like Situ Zhao Wen, Taichang Wang Wei, Weiwei Zhou Zhong, Si Lirong Shao and others, and wanted to kill them all, at this time it was Jia Xu who stood up in time and persuaded: "These people are all ministers of the Son of Heaven, why do you want to harm them?" "Successfully stopped Li Dao.

Later, Emperor Xian of the Han Dynasty sent people to ask Li Guo and others for peace, and Li Guo saw that there was no hope of regaining Emperor Xian, so he agreed to the Son of Heaven's request for peace, and put back the captured ministers, as well as some of the imperial equipment, and Jia Xu also left Li Dao.

After that, Jia Xu took refuge in other generals of the Xiliang Army, but they were not their masters after all, and they were not the final destination of their own.
