It's simple to judge whether a person is mature; just see how they perceive this world.
If they think people in this world are divided into good people and bad people, then they are immature; if they think people are divided into those who follow the rules and those who don't, then they are somewhat mature; if they realize people are divided into those who can control themselves and those who cannot, then they are mature.
Mature people will control their emotions, deal with their feelings first, and then handle matters, avoiding emotions affecting decisions and actions.
Just like now.
Zheng Qing feels he has matured.
Because he didn't turn the black gem cat into a stone out of a secret annoyance, nor did he flee and flee in a moment of panic. Instead, he stood calmly between the fox and the witch.
