Lan Tai, the author of the TV series Yongzheng Dynasty, was named Yin Gui when the 14th child of the headline signing author Kangxi Emperor was born, and was later changed to Yin Zhen by Kangxi Emperor. And Yong Zhengdi, because he hated his younger brother, directly changed Yin Zhen's original name to Yin Gui. Later, in order to avoid the word "Yin", the sons of fourteen emperors, Yong Zhengdi and Yin Zhen, were directly changed to Yunnan and Guizhou. In recent years, with the popularity of historical dramas such as Yongzheng Dynasty, Walking on Thin Ice, The Queen of the Palace and The Palace. Everyone is familiar with the deeds of various factions fighting for power and position in the last years of Kangxi. During the Republic of China, Yong Zhengdi, once regarded as a patricide usurper, also successfully "whitewashed". Now everyone knows that he is trying to clarify the official management, and he is not a bad king. Even everyone knows that the so-called "Fourteen Emperors" changed to "Four Emperors" is a false story. Yong Zhengdi is the heir to the throne chosen by Emperor Kangxi, and Yong Zhengdi is the legal heir. Admittedly, Yong Zhengdi legally inherited the throne, but Yong Zhengdi was not the first choice of Emperor Kangxi. Yong Zhengdi's brother, the14th son of Emperor Kangxi, Aisingji Orro Yinzhen, was the best heir to the throne in Emperor Kangxi's mind. It is precisely because Yin Zhen (Yunchan) is the best candidate for the throne in Emperor Kangxi's mind, so when Yong Zhengdi succeeded to the throne, there will be reports that the new emperor "secretly refused to send out an obituary" and "imperial edict attacked the throne" circulated in Beijing. The report of North Korean envoys was seven years earlier than the rumor of rectification mentioned in Yong Zhengdi's Yi Shu Lu in the seventh year of Yongzheng, which is enough to show that some people did talk about the legitimacy of Yong Zhengdi's succession at that time. In other words, if Yong Zhengdi is the best heir to the throne by default of Emperor Kangxi, how can the rumors of Yong Zhengdi's "secret funeral" and "imperial edict attacking the throne" be circulated in Beijing? The 14th Brother of Yongzheng, even the North Korean envoys, knew this rumor for only one reason: Yong Zhengdi was not the first choice in the mind of Emperor Kangxi. For a long time, Emperor Kangxi's love for Li Hong was considered as evidence that Emperor Kangxi had long recognized Yin Zhen as the first heir to the throne, but not only this evidence was not enough to be evidence, even Yong Zhengdi himself denied this statement. In fact, Emperor Kangxi had never seen his grandson, Li Hong, before he went to his fourth son, Yin Zhen, to enjoy flowers for dinner. Compared with Li Hong's children, he obviously cares more about Yin Zhen's children. Yin Zhen's first son, Hongming, "became a young servant in the imperial court", and Hongming's marriage was arranged by Emperor Kangxi. In the fifty-eighth year of Kangxi, Yin Zhen (Yun Chan) said in a letter to Emperor Kangxi: "The Emperor Tai Shang likes my minister Hongming Hong Jie very much and brought him to Jehol. All kinds of food were given to him, and the daughter of Luo Yintai, my minister's wife and brother, was betrothed to Hongming as a dowry for my minister's daughter. I heard you. I am ecstatic. But obey the instructions of the emperor. It will be more effective. " In fact, in his later years, Emperor Kangxi was very kind to many emperors and grandchildren. Hong, the son of the abandoned prince, won the favor of Emperor Kangxi in his later years. Even the report on the return of North Korean envoys recorded a rumor circulating in the capital when Emperor Kangxi died, saying that Emperor Kangxi did not forget to seal Hong as a prince before he died: "My favorite second son who abandoned the prince was sealed as a prince." As I said earlier, even I inadvertently denied it. Because it is recorded in A Record of Sejong in Qing Dynasty, after he ascended the throne, Yong Zhengdi volunteered that it was expect the unexpected who was chosen as the heir to the throne by Emperor Kangxi: (Emperor Kangxi) On November 13th last year, in a hurry, it was decided in one sentence. "Since Yong Zhengdi himself admitted that it was" sloppy ",that's settled." Where did it come from? Of course, those who oppose "Yin Zhen (Yunchan), the fourteenth son of the emperor, is the first choice of Emperor Kangxi" mainly hold that if Emperor Kangxi really recognized Yin Zhen (Yunchan) as his heir, why did he send Yin Zhen (Yunchan) to the distant northwest? I must admit that this view is reasonable in Kangxi during the Yongzheng period, because it does not conform to human nature. However, I want to say that this behavior of Emperor Kangxi can be explained. Although Emperor Kangxi was old and sickly in his later years, it did not mean that Emperor Kangxi thought he was dying. The "cold" that led to the death of Emperor Kangxi was actually the result of Emperor Kangxi's own "waves". In November, it snowed. Emperor Kangxi left Changchun Garden, traveled all over Beijing, and went to Nanyuan to live in a tent and hunt. Is this like what an old man should do when he knows that his life is dying? What is even more outrageous is that although Emperor Kangxi was unwell and had a fever when hunting, he rode a horse to blow the north wind on his way back to Changchun Garden to show his excellent health. What Emperor Kangxi did shows that he didn't feel like a "seriously ill and dying old man" before he died. On the contrary, he still feels in excellent health, otherwise he wouldn't go hunting in winter. When Emperor Kangxi sent Yin Zhen back to the northwest, he never thought that he would die so quickly. Therefore, the reason why Emperor Kangxi refused to send his heirs to the northwest was untenable. Moreover, the favorable circumstantial evidence of Emperor Kangxi's preference for Yin Zhen, the fourteenth son, was the report of western missionaries who were active in Beijing at that time. Father Dominique Parrenin, a Jesuit missionary in Beijing at that time, pointed out in his report to Rome that there is no doubt that the emperor will let him (fourteen sons) inherit the throne. " Different from people's imagination today, Emperor Kangxi had a very good attitude towards western missionaries. He also has a confidant minister named Zhao Chang, who is responsible for handling missionary affairs for him. Even on the eve of Emperor Kangxi's death, he specially ordered two missionaries who were familiar with medical skills to be diligent in Changchun Garden. Therefore, their reports and diaries are quite credible. After all, they are a third party. What's more commendable is that although the Western missionaries at that time did not like Yin Zhen, who was seriously hostile to the West and missionaries, none of them accused Yin Zhen of "usurping the throne" in his report or diary. There were a large number of missionaries in the court of Emperor Kangxi. Since missionaries thought that the first choice in Emperor Kangxi's mind was Yin Zhen, the fourteenth son of the emperor, why did they say that Yong Zhengdi himself was not a usurper? Father Dominique Parrenin explained everything in his report: "There is no doubt that the emperor will let him (fourteen sons) inherit the throne. But death came earlier than expected. Fourteen sons were in Beijing at that time. Emperor Kangxi was worried that if fourteen sons were allowed to inherit the throne, there would be turmoil within the empire during his long return. He turned his attention to his fourth son, who was born with his fourteenth mother. " This explains everything perfectly. Although Yin Zhen (Yunchan), the 14th son of Emperor Kangxi, was his first choice, Emperor Kangxi did not have a rational understanding of his physical condition. Improper exercise led to a bad cold and led to his death. When Emperor Kangxi knew that his life was running out, he found that his chosen heir was still far away in the northwest, and none of his capable children was a fuel-efficient lamp. ""In the future, I will do my best to die and put it in the Qing palace to compete with you for armor! "Qi Huangong philosopher for a kangxi emperor, of course, don't want what he said many years ago come true. In order to maintain the stability of the Qing empire and avoid the situation that philosophers really kill each other, he must appoint a new heir before he dies. This heir should have enough skills and be close enough to the capital, but not someone he hates. Under such exclusion, who gave up Yin Zhen? This is why Yong Zhengdi said "(Emperor Kangxi) at the beginning of his reign, and it was decided in a hurry." That's why there are so many rumors against Yong Zhengdi in the capital, and that's why Yin Zhen (Yunchan) was so rude at the funeral. Seriously, anyone in Yin Zhen would be disrespectful and lose the throne of the emperor, which is comparable to winning 5 million yuan. But the lottery ticket was accidentally put in his shirt pocket, and the shirt was washed by his wife, which is much more serious. To sum up, the first choice of the heir to the throne in Emperor Kangxi's mind should be the fourteenth son Yin Zhen (Yunchan), and the fourth son Yin Zhen is the emergency plan of Emperor Kangxi.
