In his later years, Kangxi wavered on the issue of heirs. He said that the ministers of the imperial court will elect a prince, which is the famous "Nine sons seize the office" in history. It also made the governors try their best to win over the ministers, making the overall atmosphere smoky, and the governors formed gangs to make the court at that time restless. At that time, the voice of Lao Ba was the highest, but it was precisely because of his numerous supporters that Kangxi felt that Lao Ba would pose a threat to his throne, so he disliked Mei more and more.

Kangxi also hated cronyism, but there is no denying that he caused the "nine sons to seize the office." Originally, he wanted the princes to compete with each other to leave the strongest, but what he didn't expect was that there were so many court officials who supported Mei and were afraid of threatening his position, so he didn't give the position of the prince to Laoba at that time. In fact, Lao Ba's position in Kangxi's heart has long since disappeared, because Lao Ba once asked a Taoist to tell his fortune. Taoist naturally praised Mei, saying that he was the chosen monarch. Later, when the emperor learned about it, he became wary of him.

Then came Kangxi's 50th birthday. May went to the mountains and caught a very fierce eagle. The eagle meant well, but something went wrong on the way. Kangxi was already a dead eagle before. Kangxi was very angry at that time, not only because it was an ominous sign, but more importantly, he felt that it was the provocation of Lao Ba to his position, so he became more alienated from Lao Ba afterwards.

Lao Ba seems to be in a hurry to get the throne, and Kangxi wanted to establish a prince at that time. Mei's move was a threat to the emperor, which naturally made Kangxi hate Mei more and more. On the contrary, the fourth son always lived in peace, but finally won the throne.
