Although china has established the system of primogeniture since the Shang Zhou Dynasty to avoid the risk of seizing the throne, it does not seem to be of much use, and whenever it faces the change of throne, it is accompanied by the shadow of the sword and light. The struggle for the throne was not only between the princes, but also between their mothers in the harem, and the various factions of the courtiers. The flesh and blood affection between the princes could not restrain this struggle at all, and the Sui Emperor Yang Guang dared to risk the world and not violate his father and brother to ascend to the throne.

In the process of the struggle for the throne, there must also be acts of pretending to be stupid. Cao Cao's youngest son, Cao Chong, died young at the age of 13 because cao Cao was too sharp and gave Cao Cao the idea of Yi Chu. In the Romance of the Three Kingdoms, Cao Cao expressed strong doubts about Cao Pi: "This is my misfortune, and Ru Cao's luck is also." The founding emperor of Northern Qi, Gao Yang, when confronted with the suspicions of his brother Gao Cheng, disguised himself as a mental retardation, and did not try to see the dagger until Gao Cheng's death and grasped all the power of his brother.
Many emperors of many dynasties would be jealous of their brothers after succeeding to the throne, such as Hu Hai of Qin II who killed all his brothers after inheriting the throne. Therefore, these imperial relatives will try to escape the suspicion of the emperor, such as Yongzheng's fifth prince Ai Xinjue Luo Hongzhi, who pretended to be crazy and sold stupidity for nearly half a century, and finally died peacefully. After his death, Qianlong also treated Hongzhi's family kindly, winning generations of wealth.
Hongzhi was born when Yongzheng was still the fourth prince, and Hongzhi's mother was the pure Yi Emperor's noble concubine Gengshi, who was only three months younger than Hongli (the future Qianlong Emperor). After Yongzheng succeeded to the throne in 1722, the clear-eyed people in the palace could see that whether it was the degree of favor or the education method arranged by Yongzheng, Hongzhi was inferior to his brother Hongli and Hongshi, that is to say, Yongzheng did not have the idea of establishing Hongzhi as the crown prince.
Because of practical reasons, Hongzhi's mother taught Hongzhi from an early age that he should protect himself and not intend to encroach on the throne, and Hongzhi also remembered his mother's teachings, causing a lot of right and wrong in the palace. When he was a teenager, Hongzhi posed as an alcoholic, and when he grew up, Heonzhao wrote the famous "Golden Bottle" in drunkenness, and in the verses, Hongzhi also showed that he hoped to stay away from the mortal world, and only wanted to indulge in the ideal of pushing cups and changing cups.
Because it was at the time when the battle for the crown prince between Hiroshi and Hiroshi was in full swing, this poem is also considered a life-saving poem by historians. Since then, Hiroshi and Hiroshi have not regarded this younger brother as competitors, so Hirohito and his brothers have a good relationship. In 1733, Hongzhi was given the title of Prince of He, and two years later he was sent to Miaojiang to serve. When Yongzheng died, Hongli became the Qianlong Emperor, and Hongzhi's behavior became more and more absurd.
Hirohito once stole tribute and wine at the ceremony, and when the other courtiers were hiding their faces and crying, Hirohito laughed while drinking; during the court, Hirohito and the Minister of Military Aircraft had friction over trivial matters and beat the Minister of Military Aircraft in front of everyone. However, Qianlong did not get angry, but instead boasted of his good nature, that is, he was a bit acute, so he sent him to the Ministry of Internal Affairs to manage affairs.
In 1770, Hongzhi died of illness, and Qianlong also held his funeral, and in front of hundreds of cultural relics officials, he rewarded The wealth that Hongzhi's descendants could not use up for several lifetimes. Therefore, historians also believe that Hongzhi is the wisest prince of Yongzheng, and the wealth of future generations is all exchanged for Hongzhi pretending to be crazy and stupid.
