My name is Chongyun. My family has practiced the art of exorcism in Liyue for many generations. Fate has been generous in allowing my path to cross with that of your distinguished self. ...Oh, no — my services are free of charge!

Exorcism uses thaumaturgy and martial arts to conquer evil. There are other means to the same end, but they are not the true way.

Before the resounding thunder, evil must cower in fear.
