What does it mean to be a young classmate and in his prime?

"My classmates are young and in their prime" means: My classmates are in their youth, radiant with youth and charming.

Excerpt:

Qia was a classmate of a young boy who was in his prime; he was full of scholarly energy and scolded Fang Qiu.

To point out the country and inspire the words, the dung is like thousands of households.

Have you ever remembered that when you hit the water in the middle of the current, the waves stopped the boat?

Translation:

The students are in their youth and in their prime; everyone is ambitious, unrestrained and powerful. Commenting on national affairs and writing these articles that stirred up turmoil and promoted purity, the warlords and bureaucrats at that time were treated like dirt. Do you remember that when we were swimming in a deep and fast river, the waves almost blocked the speeding boat?

Appreciation of the poem

The poem "Qinyuanchun·Changsha" describes the magnificent autumn colors of thousands of mountains in red, dense forests, eagles striking and fish flying, and hundreds of boats competing in the river. It recalls the student days when they guided the country, inspired words, hit the water in the middle of the stream, and stopped the flying boat. Through the description of the autumn scenery of Changsha, it expresses the revolutionary youth's emotion about the fate of the country and their heroic ambition to take the world as their own responsibility and transform the old China. The lyrics adopt the form of classical poetry, which integrates description of scenery, lyricism, and discussion. It is passionate, unrestrained, and inspiring.
