First, show weakness. When Kangxi ascended the throne, even when he was young, the military and political power was basically in the hands of four auxiliary ministers. Even when he was about to take charge of state affairs, Kangxi's own strength was still quite weak. At this time, the opposition of the four assistant ministers to Ao Bai was basically eradicated for various reasons. Sony became a coward at the critical moment. Therefore, when Kangxi felt that his strength was insufficient, he learned to show weakness and secretly accumulated his strength. Wei Dongting's training at the critical moment played a key role in eradicating Ao Bai.

Second, unity. No matter whether it is to eradicate Ao Bai or Pingsan Francisco, unity is the most used by Kangxi. At the height of Ao Bai's arrogance, Sony chose to give up. At this point, Kangxi took sourdrang dowager's advice, married Sony's granddaughter, and tied Sony, the first of the four ministers of Fuzheng, to his chariot. When San Francisco was pacified, it was used to fight and unite, and the king was dragged to his own territory. At the same time, when Taiwan Province Province was recovered, his daughter married Gedan, which was also joint and several. When one's own strength is insufficient, combination is the best way.
