This is the famous saying of the ancient Greek philosopher Heraclitus - "The sun is new every day"

(about 540 BC - about 480 BC) , the theory that all things are in a state of flux has a great influence on later generations. In his view, the picture presented by the entire world is "everything flows, and nothing is permanent." He used the metaphor of an endless river to illustrate that there is nothing in the world Everything is immovable and unchangeable. Therefore, he said, "People cannot step into the same river twice", "We both step into and not step into the same river, we both exist and do not exist", "The sun every day Everything is new." Heraclitus's famous saying illustrates the dialectics of the movement and change of things,

It means:

The sun is new every day, and life is always full of hope.< /p>
