The word 幸运 is formed by combining two characters, each contributing a layer of meaning to create a unified concept. The first character, 幸 (xìng), carries the core idea of good fortune, blessing, or happiness, a fortunate state of being. The second character, 运 (yùn), introduces the concept of movement, cycle, or destiny, like the turning of fate or luck in motion. When placed together, they conceptually merge to express the idea of "fortunate destiny" or "luck in flow", where the static state of being blessed (幸) is dynamically activated and carried forward by the forces of fate (运), resulting in the complete sense of "luck" or "good fortune".
