Character movements and expressions were indispensable elements in a novel. One could describe the character's personality, psychology, and state by describing the character's movements and expressions. The following is a paragraph describing the actions and expressions of the characters: He (the protagonist) clenched his fists and trembled slightly as if he was resisting something. His eyes were tightly shut as tears welled up in his eyes. The corners of his mouth curled up slightly as if he wanted to hide the pain in his heart, but he could not. He kept stroking his cheek with his fingers as if he was thinking about something. All of this was unusually quiet, and only the pain in his heart echoed in the air.
