平和 (píng hé) describes a calm, peaceful state — in temperament, tone, or atmosphere, it suggests tranquility and lack of disturbance. It differs from 温和 (wēn hé, 'mild, gentle'), which implies warmth and moderation (often of climate or character), and from 安详 (ān xiáng, 'serene, composed'), which focuses on a poised, meditative stillness in one's expression or demeanor.
