In fact, this should start from the social environment at that time. Kangxi was eight years old and fourteen years old. He fought at home and abroad for years, and the people were miserable. Therefore, facing the oppressive rule of Manchu, people began to miss the life of Zhu Yuanzhang in Ming Dynasty. The accompanying officials were puzzled by Kangxi's practice. Why did they go to worship the former emperor? So many officials advised Kangxi not to sacrifice.
The number of Eight Banners doll soldiers is too small, and the total population of Manchu is too small. They are really afraid of Han people dozens of times. In order to stabilize the rule, Emperor Kangxi took two preparations. On the one hand, he implemented the policy of ignorance and prohibited the further development of firearms in order to maintain the superiority of Manchu cavalry. On the other hand, he adopted a policy of appeasement. If a few people want to lead the vast majority, they must be persuaded. What if they don't?
I'm afraid the real reason is only clear to Kangxi himself, and others can only guess or have well-founded reasoning. In any case, Kangxi held an attitude of appreciation and worship to Zhu Yuanzhang, but more out of the need of political rule. There are so many people who oppose the Qing dynasty and regain their sight, and so many people scold them. People's minds are changeable, and rule is bound to be unstable. Although Shunzhi was the first to advocate the teacher's way and literature of the Han people, he became a monk in front of the emperor's loving brain.
This is also the meaning of the cry "Sun and Moon will reopen the Great Song Dynasty". Kangxi showed the world that they were also orthodox. Like Ming Taizu, he was the son of heaven who inherited three emperors and five emperors. Emperor Kangxi bowed down to Zhu Yuanzhang, and every time tens of thousands of people accompanied him to worship, the people were moved to tears. Emperor Kangxi often said that the Ming Dynasty was wiped out by bandits, and the Qing Dynasty entered the Central Plains to wipe out bandits in order to avenge the Ming Dynasty.
