Many ancient emperors used divination when choosing their heirs, and Kangxi also took advantage of this. It was in the garden that Kangxi first met Li Hong. In the conversation with Li Hong, Kangxi found that although Li Hong was a teenager, he was far-sighted, took his time when he spoke, and had a general demeanor. It is amazing that an emperor like Kangxi can have such a performance. Kangxi also likes this young emperor.
Some people say that Kangxi passed the throne to Yongzheng because he was optimistic about Li Hong, so as to pass the throne to Li Hong. However, this statement is a bit far-fetched. At that time, Yongzheng was in the prime of life, and it would be many years before he abdicated to make way for his successor. There are too many variables in this, and we all know that party struggle is very dangerous. If you are not careful, you will be doomed, and Li Hong may not make it to the end.
Li Hong's outstanding performance from childhood has a lot to do with Yongzheng's cultivation. Yongzheng was strict with his children. Kangxi likes Li Hong, because Li Hong is excellent, and he showed his wisdom when he was a teenager.
