I can't feel the dream of spring grass in the pond. The leaves in front of the steps are autumn. What do you mean?

Time flies, spring is fleeting, and autumn has quietly arrived.

This poem comes from Zhu's Persuasion Poem/Accidental Achievement in Song Dynasty. By describing the changes of spring grass in the pond and plane leaves in front of the steps, the passage of time and perishable years are expressed. The poet used the spring grass in the pond and the leaves of Platanus acerifolia as symbols, vividly expressing the flight and change of time. The poet lamented that time passed quickly, the spring dream had not yet awakened, and new grass had grown in the pond; And when autumn comes, the plane leaves have already sounded in the autumn wind.
