In the Spring and Autumn Warring States period, the Qin state relied on the succession of several generations of Ming emperors and sages, and was able to go from a backward barbarian country that was partial to a couple and stand on the ranks of the powerful countries, and after Yingzheng succeeded to the throne, he unified the six kingdoms with the increasingly powerful Qin state and established the first great unified dynasty in Chinese history, and he also became the first emperor of the ages - Qin Shi Huang.
Qin Shi Huang had outstanding achievements in his life, destroying the Six Kingdoms, creating an imperial system, unifying currency and weights and measures, building the Great Wall, etc., but there was only one thing he did not do well enough, that is, to choose heirs and ensure the inheritance of the throne.

After the completion of the great cause of unification of Qin Shi Huang, he was obsessed with the way of becoming immortals, not only sent people around to seek immortal laws and refine immortal elixirs, but also often personally went out on his own tour to find immortal medicine, and finally died on the way to the fifth eastern tour, because the incident occurred suddenly, did not reveal who the heir of the world's favorite was, and Zhao Gao, who was accompanied by him, exploited the loophole, coerced The Minister Li Si, forced the eldest son Fu Su to die, and supported the prince Hu Hai to succeed to the throne, which was for Qin II.
Zhao Gao was Hu Hai's teacher, Hu Hai obeyed him since he was a child, after Hu Hai ascended the throne, the Qin Dynasty completely fell into the Hands of Zhao, implemented strict laws and harsh government, the people at the bottom were deeply oppressed, the people were deeply resentful, anti-Qin forces rose up in various places, zhao Gao, who had always harbored evil intentions, was also actively eradicating dissidents and purging the court, feeling that the time was ripe, forcing Hu Hai to commit suicide, vainly trying to steal the world, and declaring himself emperor.
The third monarch of the Qin Dynasty, which was overlooked by the world
People in the world say that the Qin Dynasty II died, in fact, the Qin Dynasty has a third emperor, Zhao Gao wanted to stand on his own after killing Hu Hai, so he summoned the Qunchen to explore everyone's mouth, but found that the Qunchen could not accept his usurpation, he helplessly supported the establishment of the son and baby to succeed to the throne, but for the sake of future usurpation, he played the slippery head, saying that Qin Shi Huang was the emperor who ended the disputes in the world and established a unified dynasty, such as today's chaos, the child can not be called the emperor, or change to the King of Qin, so the Prince of Qin took over Hu Hai's class.
Zi Bao was also a shrewd person, he understood Zhao Gao's ambitions, but also knew that he was just his ladder over the wall, guessing that Zhao Gao would be unfavorable to himself when he fasted and worshiped his ancestors, so he conspired with his two sons and henchmen to fast and said that he was ill on the day of the fast, and Zhao Gao must personally come to invite him, and then he took Zhao Gao's life and eliminated harm for the people. On the day of the fast, Zhao Gao repeatedly sent people to invite the baby and child, but he really went to invite him personally, and the child was in the arms, so the second son of the baby who had been ambushed on the side rushed up and sent Zhao Gao to see Qin Shi Huang, and afterwards he cursed the three tribes and hung his corpse at the city gate to show the public, and the traitorous courtiers who subverted the Qin Dynasty were thus ended.
When Zi Bao reigned for 46 days, Liu Bang led an army into Guanzhong, and Zi Bao, who knew that the general trend had gone, surrendered, and the rule of the Qin Dynasty came to an end, and soon after Guan Yu defeated Liu Bang and entered Guanzhong, killing zi bao, and the era belonging to the Qin Dynasty was completely gone.
The origin of prince Qin's infant is a mystery, which has caused a lot of controversy
There are not many historical materials before the Han Dynasty, and the records of the qin princes and infants are very limited, as for his lineage, what can be examined at present is probably only the only words in the "History Volume 6 , Qin Shi Huang Benji No. 6", "Li II's brother Gongzi Bao is the King of Qin", who is the child, and what kind of kinship relationship with Yin Zheng Hu Hai has caused many controversies.
Son of Fu Su?
The brother of the second, the second is definitely Hu Hai, there is a saying that the brother is the son of the brother, and even directly refers to the son of Fu Su, which has always been the most popular saying.
However, this statement is not very likely, Fu Su is the eldest son, is the most righteous heir to the throne, the first step of Hu Hai to seize the throne is to force the death of Fu Su, and later killed all the heirs of Yingzheng, the intention is to get rid of all those who are eligible to succeed to the throne, at least can be compared with themselves, or can pose a potential threat to their own royal bloodline, if the child is the son of Fu Su, it is bound to be on the list of kills, it is impossible to give him the opportunity to succeed to the throne; and then deduce from the age, When the child killed Zhao Gao, he worked together with the two sons, that is to say, the child had two sons at this time, let alone 18 years old, that Hu Hai died in the year (207 BC) the child baby was nearly 40 years old, Qin Shi Huang was still 53 years old, Hu Hai died at the age of 24, Fu Su was the eldest son of Qin Shi Huang, still should be between 30 and 40 years old, similar to the age of the child, and even a little younger than the child, so the father-son relationship between the two was not established at all.
Therefore, the child should not be a descendant of Qin Shi Huang, let alone the son of Fu Su.
Qin Shi Huang's younger brother and Hu Hai's uncle?
Judging from the succession process of Zi Bao, Zhao Gao's usurpation of the throne could not convince the public before he pushed him to the front of the stage, proving that Zi Bao was definitely a royal bloodline, although he was not a descendant of YingZheng and was not qualified to compete with Hu Hai for the throne, but he was also a close blood relative, so he could naturally succeed to the throne when The Yin Zheng was in the line.
Therefore, it is said that "Zi Bao is the brother of Qin Shi Huang and the uncle of Hu Hai", but Yin Zheng's brotherhood is very thin, in addition to the two illegitimate brothers who were thrown to death in his swaddling, the historical records record that he only had one brother named Cheng Yu, but he also died before Qin Shi Huang unified the Six Kingdoms.
Qin Shi Huang's nephew and Hu Hai's cousin?
Some scholars have interpreted "the second brother and son gongzi baby" as the meaning of the second brother and baby, that is, the meaning of the cousin, the younger brother of The First Emperor of Qin, Cheng Yu, did have a young son who remained in the Qin State when he surrendered to Zhao in 238 BC, which was similar to the age of the child and the baby; and the history books have records about the child and the baby to Hu Hai that they should not be fratricidal, first, to show that he is not among the list of Hu Hai's purges, and he is also unrelated to the imperial throne, and it also indirectly proves that he is equal to Hu Hai's generation and is older, and he dares to give a righteous and awe-inspiring advice, and he can also retreat completely.
This is also an explanation of the tendency of individuals to cross the line, what do small partners think?
