Why did Yongzheng finally accede to the throne? Just because he has a good son.

In 61, Emperor Kangxi returned to Changchun Garden on the seventh day of November after hunting in Nanyuan. A few days later, Emperor Kangxi was seriously ill. Before he died, he called his ministers and Longkeduo, who was in charge of the imperial army in Beijing, to the imperial couch in the early hours of the morning, and announced his will: "The four sons of the emperor are precious in character. If they bow deeply, they will surely inherit the Great Unity. Follow me to the throne, follow the emperor. " Since then, the battle for the official position that stirred the Kangxi dynasty has come to an end. Why did the imperial eight sons and fourteen sons, who were sharp-edged in the battle for official positions, finally miss the throne, while the obscure imperial four sons unexpectedly won? Yong Zhengdi's ruling theory has always been questioned, but Kangxi's oral imperial edict and written testamentary edict, as strong evidence, proved the legitimacy of Yong Zhengdi's accession to the throne.

Kangxi's will finally wrote: I am old, and now my natural life will be exhausted, and my heart is happy. The son of Taizu, the son of Prince Li, is now living a peaceful life. If you can take good care of me after I die, I will feel at ease after I die. Yin, the fourth son of Prince Yong, has a noble character and is deeply similar to my trip. He will certainly inherit the throne, follow the ancestral system, wear mourning clothes for 27 days, and announce the news of his accession to the throne at home and abroad. Emperor Kangxi's testamentary edict was written in Manchu and Chinese. Even if the Chinese character "Fourteen" can be changed to "Yusi", the Manchu language is phonography, which can never be changed.

Why did Emperor Kangxi choose the emperor's fourth son as his heir? In addition to the emperor's fourth son visited warehouses in Beijing and Tong Tong before he ascended the throne, he also insisted on doing a good job of offering sacrifices to heaven from the winter solstice. According to historical records, Yin and a son, the fourth son of the emperor, were favored by Emperor Kangxi, who loved Yin's son, which was also an important reason for Yin's succession to the throne. In the spring of Kangxi's sixty-first year, that is, the last year of Emperor Kangxi's life, Prince Yong, who lived in the north of Changchun Garden, invited Emperor Kangxi, who loved peony, to the Yuanmingyuan to watch peony. Emperor Kangxi saw the beautiful calendar for the first time among the peonies. Emperor Kangxi loved Li Hong very much after meeting him, and unexpectedly returned to Yuanmingyuan after 13 days, bringing Li Hong back to the palace for self-study.

After reading Li Hong's eight characters, Emperor Kangxi instructed: "Li Hong has a rich life, which goes without saying. Divination shows that Li Hong is smart and delicate, kind and filial, and he will be proficient in civil and military affairs after his studies. There were some minor disasters when I was a child, which didn't hinder me. Hit many descendants and live a long life. " Later, Li Hong inherited the throne of Yongzheng for more than 60 years, and died in his eighties, in line with the eight-character prophecy.

Sixty-five years later, Emperor Qianlong fondly recalled his recitation of Ailian in front of his grandfather, which was deeply loved by Emperor Kangxi at that time, so even after sixty-five years, the memory of Emperor Qianlong was still so clear. Emperor Kangxi asked Prince Yin to teach him archery, and Yin Lu taught him firearms and often took him hunting. Li Hong lived up to expectations and performed well in all aspects. On his deathbed, Emperor Kangxi summoned Ma Qi, a university student, and told him that "Yin's second son is brave and good at fighting, and will be made a prince".

Before that, there was Judy, the third emperor of the Ming Dynasty. He admired Zhu Gaochi's son Zhu Zhanji and made him a great-grandson, which stabilized Zhu Gaochi's position as the Crown Prince who was inconvenient to move because of obesity.
