Yin people became princes in their forties. How could they be easily abolished by Kangxi?

It's no use building two systems. Yin Ren was born to Hesailihara, Kangxi's favorite queen. Heserihara died in childbirth after giving birth to Yin Ren. In his grief, Kangxi made Yin Ren the Crown Prince on the spot, focusing on cultivating him. In the process of growing up, Yin Yong was once very satisfied with Kangxi, but in his later years, Yin Yong's performance in the battle for the nine crown princes made Kangxi disappointed and made two mistakes. The first waste was actually the intimate contradiction between him and Huang Changzi. As a result, when he was in Zongrenfu, Yin Mi and Mei Yin Zhen, who was in charge of guarding him, got better and better. After Mimi and others made a scene in May, Kangxi came back to help Yin Mi, and Yin Zhen was one of the people here in May. In fact, this is Yin Zhen's strategy. In this way, he became a good boy who tried his best to maintain imperial power and avoid rivalry. Big Brother, Second Brother, Old Eight and Old Fourteen became more and more fierce, but they were finally enjoyed by Old Four.
