This sentence did not originally exist in ancient proverbs. It was processed by later generations on the basis of "the deceased was like a man, and he did not give up day and night." It is a common eulogy now, and its meaning is Yes: The dead have left us, and the living must live strong and well, so that the dead can rest in peace in heaven.

"The passing of time is like a man, never leaving day or night." is a famous saying of Confucius, which means that time is gone like flowing water and will never return. From the Analects of Confucius "Zihan". Confucius had a background when he said this sentence, so later generations often use it to refer to the continuous passage of time like running water, expressing emotion at the rapid changes in life and the meaning of cherishing time.

"The Analects of Confucius": Zihan said on the river: The deceased is like a man! Don't give up day and night.

Interpretation: Confucius looked at the mighty and surging river on the river bank and said: "The passing of time is like a man, not giving up day and night." It means: Time is like this rushing river, Day and night keep passing by. It means that time, like running water, will never come back, so we should cherish it more.
