Different expressions of charactersThe performance of a character could be categorized in many ways. From the perspective of description methods, there were appearance descriptions (portrait descriptions), expression descriptions, language descriptions (dialogue descriptions), action descriptions, psychological descriptions, and so on. In terms of behavior, for example, people who liked to be serious might have disharmonious relationships with others, sensitivity, impatience, and inability to afford to lose or be denied. People with high EQ might have good intentions, modesty, and low-key. They might be polite to others, pay attention to their own status, pay attention to the timing and occasion, temper themselves, and think positively about everything. From the perspective of relationships, if a man did not love a woman, he might not care about the other party's life or death, not coax the other party, not remember the other party's good, the other party's temper would be worse than the other party's, and he might create a good impression of himself and smear the other party. Different character characteristics and situations would lead to different performances.
