小说创作必须遵循张与弛的辩证规律。张是指紧张的情节,场面与心理的记述;弛是指记述舒缓的内容。前者一般用快速流动的笔法,后者一般用缓慢流动的笔法。常见的张弛变化有三种情形。 Novel creation must follow the dialectical laws of Zhang and Chi. Zhang refers to the plot of tension, scene and psychological description; relaxation refers to the description of soothing content. The former generally use fast-flowing brushwork, the latter generally with a slow flow of brushwork. There are three common types of relaxation.
