😡怒火中烧A red face with a frown and wrinkled brows. Conveys fury and rage — stronger than the plain angry face.
🤬嘴上有符号的脸A face with symbols over the mouth — the manga way of censoring swearing. Conveys anger and cursing.
🤭不说A face with a hand over the mouth. Conveys shock, surprise, or holding back a giggle — "I can't believe it".
