This sentence is: The deceased is like this, but he has never gone; the person who is full and empty is like that, but the dead are not waxing and waning. Quoted from "The Analects of Confucius·Zihan": "Zihan said on the river: 'The deceased is like a man, who does not give up day and night.'"

1. The deceased is like this, but he has not yet gone; he who is full and empty Like that, soldiers should not wax and wane.

It means: The constant flow is like the river, but it has not really passed away; the time is full and the time is waning, just like the moon, but in the end it does not increase or decrease.

If you look at things from the perspective of change, the existence of heaven and earth is just a blink of an eye; if you look at it from the perspective of change, then things and human beings are endless, so why envy the river, the bright moon and the heaven and earth? Woolen cloth! This reflects Su Shi's open-minded outlook on the universe and life. He favors looking at problems from multiple perspectives but does not agree to make them absolute. Therefore, he can maintain an open-minded, detached, optimistic and adaptable mental state even in adversity. And can be freed from the uncertainty of life and treat life rationally.

2. The deceased is like a man who never gives up day and night.

Meaning: The rushing river is so hurried! It flows day and night.

This is a famous saying by Confucius, which describes the passage of time like running water and never comes back. It expresses emotion about the rapid changes in life and the meaning of cherishing time.
