The second oldest is the most righteous, the eighth is the most virtuous, and the fourteenth is the bravest, all of them are stronger than Yongzheng, why kangxi did not choose them
The Qing Dynasty lasted for 276 years and produced 12 emperors, of which the yongzheng Emperor's ascension to the throne was the most tortuous and complicated. Kangxi was the longest-reigning emperor in Chinese history, with many heirs, which also added a lot of uncertainty to the succession to the throne, with the famous "Nine Sons and Concubines" incident.

Does jiuzi refer to the oldest Yin Zhen, the second Yin Zhen, the old third Yin Zhen, the old fourth Yin Zhen, the old eight Yin Yu, the old nine Yin Yu, and the old ten Yin? , Old Thirteen Yin Xiang and Old Fourteen Yin Yu.
Among them, the second, eighth, and fourteenth elders are considered to be popular candidates for the heir to the throne, because they have their own advantages, so that they stand out from many princes.
Yin Rong was the most righteous, his birth mother was the kangxi original empress, and his bloodline was the purest of the princes, so he was made crown prince just after he turned one year old. Because of his affection for Empress Xiaochengren, Kangxi had been personally educating Yin Rong and wanted to make him the best prince in the history of the Qing Dynasty.
However, Yin Rong was also the most miserable prince. Because he established the identity of the prince too early, Yin Rong became the object of the brothers' fire collection, and he had to give him a trip when there was nothing to do.
On the other hand, Kangxi's longevity was also a kind of torture for Yin Rong, and the 37-year life of the prince was too painful, leaving him insane, experiencing two sides and two wastes, and finally ending in more than ten years of seclusion.
The old eight is the most virtuous, saying that the old eight has the best wind evaluation among the ministers of the DPRK and is considered to be the "virtuous king". In fact, in terms of background, his birth mother Liangfei was the most shallow among all the imperial concubines, and could not bring much advantage to Yin Yu, but Yin Yu would run, which allowed him to attract many ministers and form the most powerful Eight Ye Party among the princes.
There is such a bridge section in the "Yongzheng Dynasty", the old fourth went out on business, his son suddenly fell ill, the prince Yin Rong did not pay attention, and Yin Yu took the old nine and the old ten to the Yong Prince's palace for the first time to comfort him, and also gave the imperial doctor a reward of one thousand taels. With the indifference of the prince as an inverse comparison, coupled with the fact that the rewarded imperial doctor will also praise the good of the eighth master, the father has gained a good reputation with a small move.
However, Yin Yu was bad in that his reputation was too good, and the more the ministers praised him, the more Jealous Kangxi became of him. After all, the person sitting on the throne is still Kangxi, and the courtiers all say that the old eight are good, where will Kangxi be? Is it necessary to retire early?
The fourteenth elder was the bravest, speaking of his military feats. Among all the princes, Yin Yu was the only great general king, in charge of the 200,000 Northwest Army. The Qing Dynasty princes did not have fiefs, and under normal circumstances, there were only a hundred attendants and guards, so you can imagine how big Yin Yu's military power was.
At first, Yin Yu was only a member of the Eight Masters Party, but after the gradual accumulation of military merit, he had supporters in the DPRK and became a popular candidate for the throne. Kangxi was quite fond of Yin Yu and often took him out hunting, but this did not mean that he would pass the throne to him.
Under the rule of Kangxi, the Qing Dynasty had entered a period of steady prosperity and needed a wenzhi king, not an emperor who could fight.
Compared with the second, eighth, and fourteenth elders, what is the advantage of the old fourth Yinchen? The answer can be covered in three words – keeping one's duty.
When the second eldest was stripped of his position as crown prince, the other princes were busy falling into the well, only Yin Chan was saying good things for him, pleading with Kangxi to fall from the second brother lightly; when the old eighth was wooing supporters, Yin Chan was immersed in work, well fulfilled the tasks given by Kangxi, and never pulled gangs.
These things were not conspicuous, but Kangxi saw it in his eyes, and slowly, Yin Chan left in his mind the impression of "a stable personality, a brother who loves his brothers, and a single heart for the Qing Dynasty", which is much better than those brothers who are busy fighting for the position of prince.
As a result, Yin Chan laughed to the end, became the fifth emperor of the Qing Dynasty, and then disposed of his brothers who had competed with him for the throne one by one.
Not only that, Yongzheng was deeply aware of the cruelty of the struggle for the throne, and at the beginning of his ascension to the throne, he wrote a secret decree to establish the Hongli calendar as the crown prince, hiding behind the Plaque of Zhengda Guangming in the Qianqing Palace where the courtiers were deliberating, to avoid his sons from killing each other prematurely.
