The Chinese word 光辉 (guāng huī) is a coordinating compound formed by combining two semantically similar characters: 光 (guāng), meaning "light" or "brightness", and 辉 (huī), meaning "radiance" or "splendor". Together, they create a single, more vivid and abstract concept that means "brilliance", "glory", or "magnificent light", where each component reinforces and intensifies the other to evoke a sense of dazzling brightness, often used both literally (e.g., sunlight) and metaphorically (e.g., glorious achievements).
