Born with an excess of yang (positive) energy, Chongyun has become a highly effective exorcist in Liyue — so effective to the point where he hasn't seen a spirit himself, as they immediately flee when he approaches. Due to this excess in positive energy, he's vulnerable to things that warms him — fiery events, food, drinks, clothing, the sun, and even blushing. In the event he is not able to suppress those feelings, he might enter a manic state of being excited, friendly or faint.
