2. Translation

Confucius sighed by the river: "Time flows like a river, day and night without stopping." Extended information

This is a famous saying by Confucius, which describes time flowing like water and never ending. When I came back, I felt deeply that things were changing so quickly in life, and I also felt a sense of cherishing the time.

Confucius looked up and down on the river bank, and then looked at the flowing water in the river, and he sighed. The "dead" mentioned does not have a specific reference and can be all-encompassing. Confucius looked up at the astronomy and thought about the movement of the sun and the moon and the changing of day and night, so one day went forward and one day went away. Looking down at the geography, he thought about the flowers blooming and trees falling, and the changes of the four seasons, so one year went forward and another year passed. Heaven and earth are like this, and people born between heaven and earth are no exception.
