From what angle does the poem "Yellow" express strong patriotic feelings? What is the historical and practical significance?

Poetry expresses patriotism from the perspective of praising the Yellow River and Chinese children.

This poem once aroused the anti-Japanese enthusiasm of the people of the whole country. Can it arouse the pride of China people in building a strong motherland today? .
