The difference between the "character" and "number" of ancient names was usually like this: - Character: Usually a name given by a person's parents or family at birth to indicate their identity and status. Words were usually short and often made up of one word. For example, Confucius, a famous politician and cultural celebrity in ancient China, had the word "Kong" to indicate his identity and status. - Number: It was a name given by a person to express their special identity or status. It was often related to occupation, status, achievements, etc. Numbers were usually long and made up of multiple words. For example, Li Bai, a famous cultural celebrity and poet in ancient China, had the nickname "Green Lotus Scholar", which indicated his identity and status and also expressed his talent in poetry. It was important to note that words and numbers were sometimes used at the same time. For example, Bai Juyi, a famous cultural celebrity and poet in ancient China, used the word "Xiangshan" and the word "Bai Xiangshan" at the same time. The "character" and "number" of the ancient people's names were important symbols that indicated their identity and status, reflecting their special identity and status.
