Judging from the economic, political and military achievements, literature can not ignore its own experiences in its early and later years. Cao Cao is an accomplished politician, strategist and writer in history. Because of his family background and the era in which he lived, he decided to achieve something. Cao Teng, Cao Cao's grandfather, was a eunuch when he was Emperor Huan of the Han Dynasty, and his official position was "to serve Chang Changqiu in order to pay his dues". His father Song is Teng's adopted son, and the official is Qiu. Cao Cao was born in such an official family since childhood, and he is bound to receive a good education. In addition, "be less alert and have the right to count (1)". Although he is willful and dissolute, he does not pay attention to moral cultivation and learning, and also shows his intelligence and ability to do things. Therefore, Qiao Xuan, a native of Liang, commented on him: "The world will be in chaos, and those who are doomed cannot help, and those who can be safe are in the king!" (2) "Cao Cao was recommended as Xiaolian at the age of twenty and became a Langguan. Later, he was appointed North Commandant of Luoyang County, promoted to Dunqiu County Magistrate, and was recruited into the DPRK to grant Lang. From this point of view, Cao Cao's youth was a prosperous time, and he rose to the top of the world. He successfully entered the imperial court from a local official, which gave him the opportunity to gain greater state power. Cao Cao was born in troubled times, which provided him with the opportunity to start a career. The first is the Yellow Scarf Uprising in Yuan Di and the last years of Emperor Han Ling. At the end of the Eastern Han Dynasty, the rule of the feudal dynasty was in jeopardy. The revolutionary torrent of the Yellow turban insurrectionary made the Liu Dynasty unstoppable. So local governors had to be dispatched to suppress the peasant movement, and Cao Cao was appointed as a captain riding a horse to crusade against the peasant rebels in Yingchuan. Later, he was promoted to Jinan. From then on, the feudal lords from all walks of life occupied one side and stood on their own feet as kings. Dong Zhuo entered Beijing, abolished the younger emperor, established the Han emperor, and the capital Luoyang was in chaos. Cao Cao and Yuan Shao joined forces with various governors to crusade against Dong Zhuo. Although Dong Zhuo was removed, Yuan Shao, Yuan Shu, Gongsun Zan and Lyu3 bu4 in the north have formed some powerful governors and occupied one side. Cao Cao sold the property here, recruited volunteers and gradually expanded his power. Later, in the process of encirclement and suppression of the Yellow Scarf Army, more than 300,000 soldiers were reduced and their elite was incorporated into the so-called "Qingzhou Army". Plus the support of his brothers Coss, Cao Hong, Xia, Xiahou () and so on; Yu Xun, Cheng Yu, Jia Xu and others made suggestions and wiped out the remaining Yellow Scarf Army. Defeated the separatist forces such as Lu Bu, Tao Qian, Zhang Miao and Zhang Xiu, and gradually gained powerful armed forces, becoming an important political group that ruled the north during the Three Kingdoms period. Cao Cao's victory in the separatist armed struggle was based on an enlightened political struggle. First of all, Cao Cao realized the important role of feudal emperors in political struggle while carrying out armed struggle. Encouraged by Xun and Cheng Yu, Cao Cao sent Cao Hong to the west to meet Xian Di. After Cao Cao entered Luoyang, he personally appeared before Xian Di. He was promoted to General Town East, appointed Fei Houting, recorded history and always led state affairs. Cao Cao moved the capital to Xuchang. From then on, he had an excuse to give orders and a deterrent among the princes. This is what people call "seizing the emperor to make the princes", which is also one of the important reasons why Cao Cao Can gained the upper hand in the separatist regime. Secondly, as a politician, Cao Cao understands and cares about (at least thinks of) people's sufferings. Years of war have seriously damaged production, coupled with natural disasters, such as "there are many Russians, and there is no way to distribute food", and there is even no place to raise military food for war. Cao Cao adopted the suggestions of Zhao Zuo, Han Hao and others to cultivate land. Loans for plowing cattle and cultivated land provided to farmers are divided into six official cows and four private cows. The purpose of reclaiming farmland is mainly to meet the needs of military food, but also to solve the livelihood of some farmers who have no cattle and no fields. The land reclamation tax is paid directly to officials, which also avoids the exploitation of landlords, and the rations will not be entirely borne by farmers. Ensuring the army's food is not only beneficial to the war, but also reduces the arbitrary plunder of the army, which is beneficial to the people in any case. At the same time, Cao cares about the sufferings of the people. After defeating Yuan Shao, he ordered: "Hebei suffers from Yuan's difficulties, which makes it not to rent taxes this year! "Because of the war, the people were exempted from the rent tax for one year. Cao Cao also specially stipulated: "From the item, the number of conscripts, or in case of epidemic, officials died, family members were dissatisfied, and the people were displaced. How can the benevolent be happy? "I have to. So that the families of the deceased can't survive without a legacy, the county officials have no worries, and the chief sympathizes, so that I mean (3) "The government provides them with food, and the chief should visit them often. In terms of treating the people, Cao Cao also ordered that "all women who have reached the age of 70 and have no husband or son, are under the age of 12, have no parents or brothers, are blind, lose their labor force, have no wife, children, father, brother or industry, and the state will support them for life." "Command counties to advocate and attach importance to the study of literature and classics and school construction. 500 counties should set up academic officers to select outstanding local children for education. (4) "No matter what the conditions and implementation were at that time, Cao Cao's policy of developing production, caring for people's sufferings and developing education was very enlightened and progressive among the feudal ruling class, and it would certainly be supported and welcomed by the people. Cao Cao is also a strategist. He is good at fighting. The Three Kingdoms period was a period of war. There are wars almost everywhere, and there are wars every day. Many governors expanded their sphere of influence during the war. The reason why Cao Cao can stand out from the crowd is inseparable from his military talent. According to historical records, he is very good at directing wars. Guo Jia, an adviser, commented that he could "defeat the masses with fewer troops and use his troops as a god" when analyzing Ten Victory Proposals. Take Zhang Xiu as an example. Cao Cao surrounded Zhang Xiu in Maoxian. In May, Liu Biao sent troops to rescue and cut off Cao Jun's back road .. Cao Cao wanted to retreat, and Zhang Xiujun chased him. It was difficult for Cao Jun to move forward, so he launched his company's battle array and gradually advanced. Cao Cao wrote to Yu Xun, "Shu soldiers are coming after me. Although I only March a few miles every day, I estimate that when I arrive in Anzhong County, I will definitely defeat Zhang Xiu. " In anxian county, Zhang Xiu and Liu Biao's troops were in one place, and Cao Jun was flanked from front to back. Cao Cao dug an underground passage in a dangerous place overnight, carried all the trench away and ambushed the raiders. At dawn, the enemy thought that Cao Bing had retreated, so the whole army pursued him. Cao Jun sent infantry and cavalry to ambush and defeated Zhang Xiu. It can be seen that Cao Cao's ability to fight like a god. There is also a famous official.
