Why did Kangxi change his name to Bao Bodhisattva?

I hope Yongzheng can be as merciful as a bodhisattva and avoid Wang Hong's death.

In March of the fourth year of Yongzheng, the titles of Eight Lords and Nine Lords were cut. Except for the Yellow Belt, all the eight lords changed their names to Akina, which means fish on the mountain, and renamed their sons Bao Bodhisattva, so that Yongzheng could be merciful like a Bodhisattva and avoid death. Nine princes refused to change their names, and Yongzheng changed his name to Seth Black, meaning nuisance.

Evaluation:

All aspects of Yi Yin's situation are enough to show that he is by no means a "weak and timid", "soft-hearted" and "easily forced" person, but he has considerable leadership ability and is good at pleasing people. On most occasions, he has strong restraint and is relatively calm. Yin Zuo Wei's style is flexible and smooth, and he doesn't stick to rules and titles.

This deviance is another outstanding feature that distinguishes him from other princes, and it is also one of the reasons why he is very popular and supported by all ministers.
