As we all know, Daqin Empire is a vassal country with a long history in China. During the 500-year-long growth of Daqin Empire, Qin used talents in an eclectic way, which was the ultimate secret of Qin's ultimate rise and unification of China.

For example, Qin Mugong reused "five-year-old doctor" Bai Lixi; Qin Xiaogong appointed Shang Yang to implement the "Shang Yang Reform"; Qin reused Zhang Yi, a disciple of Ghost Valley. Zhao Haoqi of the State of Qin reused Fan Sui, who was "attacking far and defending near"; Qin Shihuang attached great importance to legalists Han Fei, Li Si and others. It was Qin's eclectic reuse of talents in the past dynasties that made Qin gradually prosperous and became the most prosperous country among many countries in the Warring States period, laying a solid foundation for Qin's unification of the world.

With the efforts of the ancestors of Qin State, after Qin Shihuang acceded to the throne, he re-used the Legalist ideology, unified Lian Heng, and re-used generals Tian Lei, Meng Tian, Wang Jian and Zhang Han. After more than ten years' efforts, Qi, Chu, Yan, Han, Zhao, Wei and other countries were finally eliminated one by one, and the great cause of reunifying China was completed.

After Qin Shihuang unified the world, the Great Wall, Lingqu, county and unified measurement were built, which not only unified the territory of China, but also gradually formed the unified whole of China's cultural habits, initially formed China's thought of "great unification" and laid the basic framework of modern China. Qin Shihuang deserves to be "an emperor through the ages"!

Then, since the Daqin Empire was powerful, why did it collapse overnight? What mistakes did Qin Shihuang make?

Even he didn't make a prince until he died! Then why didn't Qin Shihuang set up a prince?

First, Qin Shihuang and his eldest son Fu Su had "political differences"

After Qin unified the whole country, Qin Shihuang believed that when the world was just settled, it was really turbulent and unstable, and the eliminated nobles would inevitably be unwilling to fail, and they would lurk in the dark, plotting to restore the country and be enemies with the court. They must adhere to strict laws and be alert to the people's rebellion, so as to better govern the country and make the people afraid, so as not to rebel; Zi Fu Su believes that since the world has been unified, after a long campaign, we should "share the interest with the people", give up "harsh laws" and govern the country with loose policies.

In addition, Qin Shihuang wanted to kill those who abused him and his mother in Zhao, and Fu Su stood up against it and asked for forgiveness. Qin Shihuang wanted to build a mausoleum, and Fu Su advised his father not to spend too much "wealth"; Qin Shihuang wanted to build Epang Palace, but Fu Su dissuaded him.

At that time, Fu Su was deeply influenced by Confucianism and was "lenient", which really prevented his father from doing many absurd things of the first emperor and won him the reputation of "wise man". However, it also made his father Qin Shihuang, a power-hungry and arbitrary "legalist", inevitably dissatisfied with Fu Su, resulting in contradictions.

When the imperial power was inviolable, Qin Shihuang punished Fu Su and "demoted" him as the military commander in Meng Tian, responsible for "repairing the Great Wall and preventing the Huns".

Second, Qin Shihuang wanted to experience the "future prince"

Although the first emperor and his eldest son Fu Su did have "political differences" and various contradictions, the first emperor was satisfied with his eldest son.

Fu Su is smart and studious, resolute and brave, and has the reputation of "wise man". However, after all, Fu Su's political views on governing the country are reasonable. To some extent, the first emperor also agreed with Fu Su that "the people should live in peace" and should "share the interest with the people". But the first emperor thought it was not time, because the first emperor understood that although the whole country was unified, there were barbarians in the south, Xiongnu in the north and domestic ones.

Qin Shihuang punished Fu Su in Meng Tian and reduced him to the rank of army commander, which was really "self-belittling". He wants to experience his eldest son and his beloved son. Only when he really had the ability to command the army and mastered the military power did Qin Shihuang trust to hand over the country to Fuxi. When Qin Shihuang sent Fu Su to Meng Tian as the military commander, he actually put hundreds of thousands of troops in the north who resisted Xiongnu under Fu Su's command, which gave Fu Su the merits of resisting Xiongnu invasion and was also conducive to Fu Su taking over national sovereignty in the future.

However, Qin Shihuang underestimated the "temptation of power" and trusted his minions Reese and Zhao Gao by mistake. After all, the legalist Reese and the greedy Zhao Gao were dissatisfied with Fu Su, who believed in Confucianism. Reese and Zhao Gao colluded with Hu Hai to tamper with the first emperor's testament for their own power, forcing Fu Su and Meng Tian to commit suicide, which made Hu Hai ascend to the throne. The state of Qin not only lost a general who can be good at fighting, but also lost a "wise" heir.

After Hu Hai acceded to the throne, the extravagance became more and more serious, causing strong dissatisfaction among all parties in the ruling and opposition parties. Finally, officials forced the people to revolt. Chen Guang shouted the slogan "I'd rather have seed" in osawa Township, rose up against Qin, and set off the famous "Daze Township Uprising". Then, four directions moved, and uprisings were launched one after another in various places. The famous leaders of the Rebel Army are Chu Xiangyu and Liu Bang, curator of Surabaya Pavilion. In the end, the powerful Daqin Empire, which has been inherited for more than 500 years, died in the mighty people's uprising.

Daqin Empire belongs to the earth, and it collapsed overnight because Qin Shihuang made the biggest mistake-he died without a prince. It is precisely because of this mistake that his dream of "a thousand generations" of the Qin Empire was shattered, ruining the country that has been passed down for hundreds of years and ruining the prosperous times. What a pity!
