In the Three Kingdoms, there were many "good guard" warriors, with Shu Han having Huo Jun and Cao Wei having Hao Zhao. Hao Zhao, who is nine feet long, is good at shooting ape arms, and his military ability is very prominent. Originally, Zhen defended Hexi, but because Zhuge Liang led an army to invade the territory, Sima Yi recommended Hao Zhao to the Wei emperor Cao Rui, made him a general of Zhenxi, and asked him to lead troops to guard Chen Cang to resist Zhuge Liang's march.

Speaking of the personal feud between Hao Zhao and Zhuge Liang, it also stems from this second Northern Expedition. In the twelfth year of Jianxing, Zhuge Liang and Eastern Wu agreed to jointly attack Cao Wei. Zhuge Liang led the Shu army out of the pass and surrounded Chen Cang. In the face of Hao Zhao, who was sent by Cao Rui to guard Chen Cang, Zhuge Liang and others attached great importance to it. Because, in the investigation of the Shu army's scouts, it was not difficult to find that Hao Zhao had arranged Chen Cangcheng's defenses very strictly.
The Shu soldiers sent a sentry to Chen Cang, returned to Kong Ming, and said: "Chen Cangkou has built a city, with the general Hao Zhao guarding the guards, deep ditches and high fortresses, and rows of antlers, which is very strict. ”
That is to say, not only is it very difficult for the horse infantry to attack, but even if the cavalry attacks, it will be blocked by antlers, and it is not easy for the Shu army to break through a small opening. However, Zhuge Liang believed that the north of Chen Cang was a street pavilion, and only by taking Chen Cang could the Shu army advance and retreat in the later period. Therefore, he resolutely ordered Wei Yan to lead an army to attack Chen Cang. But unfortunately, whether the Shu army used cloud ladders, rushing cars, or transporting soil to fill in the trenches, they were all cracked by Hao Zhao.
It was precisely because of this that the Shu army attacked Chen Cang for more than twenty days without being able to break through the city. Therefore, Hao Zhao successfully resisted the pace of Zhuge Liang's Northern Expedition and made Zhuge Liang's Second Northern Expedition fail.
From this point on, the interpretation and the history of the main history began to differ. In the main history, after Hao Zhao resisted Zhuge Liang's Second Northern Expedition, he was recalled to Luoyang by the Wei Ming Emperor Cao Rui and given the title of Marquis of Guannei. But soon, Hao Zhao fell ill and died.
In the rendition, during Zhuge Liang's Third Northern Expedition, Hao Zhao led his troops to garrison Chen Cang, still dueling with Zhuge Liang. Soon, Hao Zhao's condition worsened. After Zhuge Liang learned that Hao Zhao was too ill to command the army, he hurriedly took advantage of Zhang Gao's change of defense and increased his attack on Chen Cang. When the Shu army broke through the city tower and entered Chen Cangcheng, Hao Zhao, who had learned the news, was scared to death.
If you look at it according to this statement of yanyi, Zhuge Liang must have ended the feud between himself and Hao Zhao. After all, no matter how good Hao Zhao was, he was also scared to death after hearing that the Shu army had entered the city. Of course, the plot of the novel, Hao Zhao successfully resisted Zhuge Liang's Northern Expedition in the second time, and in the third time wrote that Hao Zhao was scared to death, to a certain extent, it also highlighted the effect of Zhuge Liang's great reputation and the "destiny of Heaven" of Shu Han.
