What does "the infinite treasure in the poetry of time" mean?

Time is life, we must cherish time and cherish every minute and every second around us.

The whole poem

Time flows like a river that never stops,

it flows past everyone,

and continues to flow to places far, far away.

Hard-working people scoop up endless treasures from the "small river",

Lazy people can only scoop up regrets and disappointments.

Time is limited, people Be diligent and rely on your own hands to fight
