What grade is "occasionally" Zhu's primary school?

I am in the fourth grade of Zhu Xiaoxue.

My Success is a seven-character quatrain written by Zhu, a philosopher in the Southern Song Dynasty. Full text: Young people are easy to get old, but difficult to learn. Before the sweet spring grass grows in the pond, the plane leaves in front of the steps have rustled in the autumn wind.

The days of youth are easy to pass, but learning is difficult to succeed, so cherish every inch of time and don't let it go easily. Before I woke up from the bright spring, the leaves of plane trees rustled in the autumn wind in front of the steps.

Full text appreciation:

"Young people are easy to learn when they are old, but difficult to succeed. An inch of time is not light. " This is the poet's personal experience to warn young people that life is easy to get old and learning is difficult, so we must cherish time. Because it is easy to get old, it is not light, which shows the importance of cherishing time. Explain that we should cherish the beautiful years, study hard, and never let precious time slip away from us in vain.

"I didn't feel the dream of spring grass in the pond. The leaves in front of the steps are already autumn." With a keen and delicate brushwork, the poet draws lessons from the beautiful images in previous poems and combines his deep feelings about "a teenager is easy to get old, and a scholar is excellent to be an official".

It is very appropriate to compare the degree of how time flies and how easily years pass with sleepless dreams and the voice of Ye Qiu, so as to increase the power of encouragement; Thus, it can more vividly reflect the theme of "An inch of time is not light" and leave a deep and unforgettable impression on readers.
