What does light time mean

Light time is often used to describe the passage of time and the change of years. In traditional Chinese culture, light time is often regarded as a valuable asset, as it represents time and opportunity and can influence people's destiny and life. At the same time, light time is also often used to describe the transience and impermanence of life, warning people to cherish time, seize opportunities and live up to their youthful years.

In daily life, people often use words like "time flies like an arrow" and "years fly like a shuttle" to describe the rapid passage of time and the shortness of life.
