Why did Qin Shihuang rule the whole country?

Qin Shihuang (259 BC-2 BC10) was the first founding emperor of the Qin Dynasty to unify China. Later generations called it "the emperor of the ages" and named it after his surname. Born in Zhao, also known as. 13 years old, king. At the age of 22, he was crowned as an adult in Yongcheng, the old capital, and officially ascended the throne. At the age of 39, he completed the historic cause of reunifying China and proclaimed himself emperor. In the first 246 years, the King of Qin won the throne because the young government was in charge of the Empress Dowager and the Prime Ministers Lv Buwei and Lao Ai. In the first 238 years (the ninth year of the King of Qin), the King of Qin ruled personally, getting rid of Lu, Mao and others, and reusing Li Si and Mao. From 230 BC to the first 22 1 year, the six countries of Korea, Zhao, Wei, Chu, Yan and Qi were destroyed successively, thus completing the great cause of reunifying the whole country and establishing the first great unification. After reunification, Ying Zheng, the king of Qin, thought that his contribution was better than the previous three emperors and five emperors, and he called himself the "emperor". A ruler is called Qin Ershi. According to Sima Qian's Biography of Historical Records of Lv Buwei, Qin Shihuang's mother was the daughter of general Zhao, and she was a concubine before giving Qin Shihuang. For political purposes, Lv Buwei gave Zhao Ji, who was pregnant, to an alien (that is, the king of Qin Zhuang). Later, Zhao Ji became pregnant in December and gave birth to Ying Zheng, but she was actually the illegitimate child of Lv Buwei and Zhao Ji. According to the research results of modern medicine [source request], it is rare to be pregnant for twelve months; At the same time, menopause as a sign of pregnancy will also be suspected by strangers. So it is possible that Sima Qian made mistakes in Historical Records. ) Ying Zheng is an underrated son of protons. He spent his boyhood in Handan, the capital of Zhao. At this time, the aliens have returned to Qin through mediation and recognized Mrs. Huayang as their mother. After many political struggles, he finally won the trust of Huayang. Spent a lot of energy and money to take Evonne and her son back to Qin, and Ying Zheng started his political career in Qin king Palace. In the third year of King Zhuangxiang (247 BC), King Zhuangxiang died and Ying Zheng ascended the throne as King of Qin. When he acceded to the throne, because he was young, national politics was dominated by Prime Minister Lv Buwei, and Lv Buwei was honored as Guan Zhong. Lv Buwei not only controls the imperial court, but also has an affair with the Empress Dowager (Evonne). Seeing that Qin Shihuang was old and afraid of being discovered by him, he gave false eunuch Laoyi to the Queen Mother. As a result, the Queen Mother gave birth to two illegitimate children, and Laoyi, a false eunuch, assumed the title of Wangfu, made a long letter, owned Yang Shan, Taiyuan and other places, and collected his own henchmen. Laoai has been operating in Yongcheng for many years and has established a huge force. In the first 238 years, Qin Shihuang held a coronation ceremony at Yongnian Palace in Yongcheng. Lao Ai used the decree to launch a rebellion and attack the Hall of Prayer for the New Year. Qin Shihuang had already arranged 3,000 chosen men in the Qi Dynasty Palace to defeat the rebels. Lao Ai moved to Xianyang Palace, where there was already an army. Lao Ai fled alone and was arrested soon. Qin Shihuang dismembered Lao Ai's five horses and made them public. Put his mother Zhao Ji in the Luyang Palace in Yongcheng. Qin Shihuang then dismissed Lv Buwei and exiled Lv Buwei to Bashu. Later, although the nobles of the State of Qin listened to their words and issued an "expulsion order" to expel the diners from the six countries, they were discouraged by Li Si's "persuasion and expulsion" and later appointed Wei Liaozi, Li Si and others. From 230 years ago to 22 1 year ago, Qin Shihuang adopted the strategy of far-reaching and near-attacking, divided and alienated from each other, and launched the war of Qin destroying six countries. Qin Shihuang destroyed Korea in 17 years, Zhao in 18 years, Wei in 22 years, Chu in 24 years, Yan in 25 years and Qi in 26 years. Finally, the first unified, multi-ethnic and autocratic centralized state in the history of China, the Qin Empire, was established. After the Qin dynasty destroyed the six countries, it began to build the Great Wall in the north, collecting more than 400 thousand civilian workers every year. At that time, the productivity was extremely low, so men could not eat bitterness and women could not knit clothes. So many people are recruited to engage in unproductive labor, and the only result is that the death toll cannot be counted. Thousands of miles away, there are corpses everywhere, and rivers of blood are flowing. It is not surprising that five out of ten households want to rebel. The folklore of "Meng Jiangnu cried down the Great Wall" also reflects the complaints of ordinary people about the construction of the Great Wall from one side. The Great Wall built at that time was not the Great Wall we see today (the Great Wall was built in the Ming Dynasty), but a rather unstable rammed earth wall. Qin Changcheng's main purpose is to mark the boundary between Xiongnu and Xiongnu, but it has no substantive defensive function. Moreover, the Xiongnu was not strong at that time, and the first emperor sent Meng Tian to send hundreds of troops to attack the Xiongnu. Later generations commented on this: "attack from afar, be greedy from outside, be broad without worrying about its harm." Not long after Meng Tian's death, Xiongnu easily crossed Qin Changcheng, not only recovered the original lost land, but also occupied Yan, Dai and other counties. To sum up, it is still a controversial topic whether the Great Wall itself is meaningful in the war against nomadic people in later generations, but at least in the Qin Shihuang era, it did not play any role except wasting national strength. Launched an incident of burning books and burying Confucianism. At that time, hundreds of schools of thought contended in the society, which seriously hindered Qin Shihuang's thought of unifying the people of the six countries and threatened the rule of the Qin Dynasty. So, in order to unify the thoughts of the people of the original six countries, Qin Shihuang began to destroy all hundred schools of thought's works except the legalist, until the demise of the Qin Dynasty in 206 BC, which was known as "burning books". In the second year after the book burning began, that is, 2 12 BC, Qin Shihuang killed more than 460 Confucian scholars and alchemists in Xianyang, Qin Dou at that time, in order to further repel different political ideas and opinions, which was known as "pit Confucianism" in history. Before Qin Shihuang unified the six countries, there were many palaces, but during the unification of the six countries, the construction was even bigger. Every time a country is destroyed, it is necessary to copy its palace buildings near Xianyang, and the total area has reached an amazing level. The whole Guanzhong area, from the north of Weihe River to the east of Yong Men, to the Jinghe area, is full of palaces. After reunification, Epang Palace (also known as Gong Chao, formerly known as Epang Palace) was built on the south bank of Weihe River, and more than 700,000 migrant workers are employed every year. Although some people argue that these people are guilty, the proportion of 700 thousand is amazing compared with the national population of only 20 million at that time. The Forbidden City can hold100000 people, and it needs horses and chariots to transport food and wine inside. The area of only one vestibule is 693m from east to west, with a width of 116m from north to south, with a pedestal as high as11.65m and seating capacity of110,000 people. However, the archaeological team of Epang Palace, which was jointly composed of the Institute of Archaeology of Chinese Academy of Social Sciences and the Institute of Cultural Relics Protection and Archaeology of Xi City, found that Epang Palace was not built at all, and the foundation of this palace was only completed in the Qin Dynasty.
