Who took Kangxi's place?
In the later years of Kangxi's reign, Yongzheng and his brothers had fought, and there were rumours that he had usurped the throne(most of the rumours believe that Yongzheng's brother Yingzhen (Kangxi's 14th son) is the real successor of Kangxi Emperor, the reason why Yingzhen failed to sit on the throne is because Yongzheng and his confidant Keduo Long tampered the content of Kangxi's testament at the night when Kangxi passed away), a charge for which there is little evidence.
