Time is life, that is to say, cherishing time is like cherishing life. Man's time is limited, and life is made up of limited time. Therefore, time is life, and cherishing time is cherishing life. Just like a person's life can't be resurrected after death, "the sun and the moon fly like a shuttle, time flies", and time can't go back. Therefore, people can be generous to everything in life, but not to time; Don't be stingy with anything except time. Cherish life, we must cherish time. In other words, to cherish time is to cherish life.

Time is life, and it is also reflected in the importance of specific time. For example, a seriously ill patient, when his illness breaks out, it is particularly important to strive for rescue time. Fighting for a minute may save this person's life, and delaying for a minute may lead to the end of this person's life. The same is true for the seriously injured and the sick. In this sense, time is life.
