The word 时光 (shíguāng) is formed by combining two characters that each evoke a fundamental aspect of existence: 时 (shí), meaning "time", "season", or "era", and 光 (guāng), meaning "light", "ray", or "brightness". Together, they create a compound that conceptually fuses the abstract, measured passage of time with the tangible, visible quality of light, poetically envisioning time as something luminous that flows, illuminates, and can be witnessed or felt, much like sunlight passing through a day or the glow of a particular era. It transforms the invisible phenomenon of time into a metaphorically visible and experiential essence.
