Qingzhou, the Linzi (Linzi) city in the territory of Qiguo County, now looks like a majestic city and a big Guo posture, just a little arrogantly looking at the Dongyue Taishan in the southwest of the Qingzhou Plain, it seems to be preaching to the world the relationship between the opposition and unity between the lofty mountains and the stretch of the vast plain.

Taishan County belonged to Yanzhou, and there were several fierce generals under Cao Cao, such as Pingdong General Cao Ren, Anyuan General Yu Ban and Yangwu General Li Dian. These generals are all wise and brave and extraordinary in the use of soldiers, and ordinary people have nothing to do at all.

Pingdong general Cao Ren, the word filial piety, Cao Cao's younger brother, good archery and horse riding and shooting, did not practice inspection when he was young, and after following Lao Cao to become a general in the army, he became strict and conscientious. Whether it is in the official history records of later generations or Lao Luo's "Romance of the Three Kingdoms", Cao Ren is a well-deserved first meritorious general under Cao Cao.

In the official history, when Cao Cao attacked Yuan Shu, Cao Ren won a lot. Later, Tao Qian's army and Tao Qian's general Lu You were defeated, Juyang was conquered, and Lu Bu's general Liu He was captured. In the Battle of Guandu, he defeated Yuan Shaojun in the Battle of Jiluo Mountain. After the defeat of Cao's army in Chibi, Cao Ren defended Jiangling and Zhou Yu for a year, which won valuable time for Cao Cao to regroup. In the battle of Weinan, Ma Chao was broken, and Su Bo, Tian Yin, and Hou Yin were defeated, and in the battle of Xiangfan and Wei Shu, they blocked the attack of Guan Yu, who was unstoppable at that time.

After Cao Ren's death, he was called a loyal marquis, according to the "Historical Records: The Law Explained": "The danger is to be loyal." The danger is not to be spared. Therefore, in the Cao Wei Dynasty, "loyalty" was really a great reputation, and only Xiahoudun and Cao Ren were so highly evaluated. "Fu Zi" has clouds: "Cao Da Sima Zhiyong, Meng Ben, Xia Yufu Jiaye." Zhang Liao was secondary. Zhang Wenyuan, who made Jiangdong children dare not cry at night, was also second to Cao Da Sima.

Cao Ren is better than Xiahoudun in terms of merit, higher than Xiahou Yuan in terms of fame, and close to the "five good generals" in the party family, looking at his life, he can really be said to be the first meritorious general in Cao Wei's camp.

General Anyuan is forbidden, and the text is a native of Taishan Juping (now Tai'annan, Shandong). Later generations called him and Zhang Liao, Le Jin, Zhang He, and Xu Huang as "five good generals". The official is the left general, and he is fake. If it weren't for Yu Ban's surrender after losing to Guan Yu in the Battle of Xiangfan, a generation of famous generals would not have been able to protect his later years, and he would not have been called "Li Hou" after his death.

If the combat courage and composure are enough to make Yu Ban among the famous generals, then Yu Ban's overall situation and political acumen have established his unshakable position in Lao Cao's camp.

In the forbidden army, under the law, very strict, "Three Kingdoms" recorded: at that time, it was forbidden to be with Zhang Liao, Le Jin, Zhang He, Xu Huang as famous generals, Taizu every expedition, Xian handed the line of the army, but also for the refusal; Because Yu Ban's army was too strict, so that his subordinates had nothing to fish, Cao Cao was obviously very aware of Yu Ban's style, so he took special care of Yu Ban every time he rewarded him, so as not to let "honest people suffer".

Although Yu Ban did not please his subordinates because he was too strict, because of Yu Ban's impartiality and selflessness, he had a very high prestige in the army. To what extent, "Three Kingdoms" records one thing: Cao Cao wanted to cut off his military power because he was jealous of Zhu Ling, but this was a very likely thing that would cause a mutiny, and after thinking twice, he decided to send Yu Ban to execute, and Yu Ban took Cao Cao's warrant and dozens of soldiers to Zhu Ling's military camp on horseback, and took the danger alone to carry out Cao Cao's orders. At that time, many soldiers under Zhu Ling were afraid of the ban, but none of them dared to resist. From this incident, we can see the prestige of the forbidden in the Cao army, and even faintly feel a domineering and murderous aura revealed in the forbidden bones.

Yangwu General Li Dian, the word Mancheng. A native of Juye County, Shanyang County (now Juye, Shandong). Li Dian is well aware of righteousness, does not compete with others, advocates learning and noble elegance, respects erudite people, and is known as an elder in the army. Li Dian had the style of an elder, and he was an official to a general, and died at the age of thirty-six. After Emperor Wen of Wei Cao Pi succeeded to the throne, he was posthumously named "Marquis of Kuo".

If a person is only thirty-six years old and is called an elder by his subordinates, his character and character can be imagined. Because Li Dian does not compete with the generals, this has caused him to not be too high, and if Li Dian does not die early, he will definitely be able to achieve higher achievements.

Cao Cao sent the general Cao Ren as the commander in one go, supplemented by the deputy generals Ban and Li Dian, and hoarded heavy troops in the northeast and due east directions of Taishan County to guard against the coercion from Qingzhou, just because there was a fierce man in Linzi City of Qi not far from Taishan County that Cao Cao was very afraid of, and he was Zhao Zilong, the commander of the Qingzhou Army.

General Zhao Zilong was born in the same year as Zhao Xing, the king of Pingxi, a few months younger, originally Zhao Guochang's younger brother, and at the age of sixteen, he became a righteous brother with Zhao Xing, and since then he has become one of Zhao Xing's most relied on generals, and has laid an endless foundation for Zhao Xing to come and go in the rain.

Zhao Yun has Xu Huang's calm and cautious, and Guan Yu's sharpness is unmatched, and he is generous and benevolent by nature and is not good at making great achievements, as for his absolute loyalty and unconditional support for Zhao Xing, it is even more needless to describe it.

Before Zhao Yun came to Qingzhou, almost none of the generals under Lao Cao had confronted him head-on, but Zhao Yun guarded Huguan with less than 10,000 troops and stopped the 130,000 allied troops on Zhao Dong Road to the east of Shangdang, but it really made Lao Cao dare not despise this "jade-faced tiger".

In terms of personal force alone, Zhao Yun was able to make the flying general Lu Bu deflated; in terms of commanding the army to fight, Zhao Yun led 5,000 blue wolf troops into the desert in the north for thousands of miles, killed the Xianbei people who were still very powerful at that time, and gave the northern part of Bingzhou eight years of peace in the first battle.

It's not that Cao Cao doesn't have confidence in his brothers, it's that Zhao Yun's coercion on Yanzhou is too great. Just imagine, once Zhao Yun commanded the "outlaw general" Gao Shun to open the way in front with 40,000 Donglai troops with the title of invincible, and he himself led 20,000 flying tiger troops to attack Chen Liu, the hinterland of Yanzhou, who under Cao Cao could stop Zhao Yun's sharpness?

If Zhang Liao, the fifth brother of Zhao Yun Jieyi, who was in Xuzhou, followed over to join in the fun, just these two fierce men would be able to turn Yanzhou, which Cao Cao had worked hard for more than ten years, into a place of four wars within a few months.

It was precisely because of the invisible coercion of the "jade-faced tiger" Zhao Yun that Cao Cao ordered the general Cao Ren to set up a huge army formation called the "Eight Gate Golden Lock" in Laiwu County, northeast of Taishan County, to always guard against possible attacks from within Linzi City.

Cao Ren's Yu Ban led an army to defend thirty miles west of Laiwu, and Li Dian led another army to defend thirty miles southeast of Laiwu.
