"The boundless fallen trees rustle down, and the endless Yangtze River rolls in" are some famous sentences through the ages about the solemn and solemn autumn scenery, and the vast and empty scenery. Can the fallen trees in the sentence be changed to fallen leaves?

No

This couplet is written from a broad perspective, with a magnificent realm, integrating vision and hearing into one picture.

Writing about the solemn and solemn, empty and vast scenery in autumn, one sentence looks up and the other looks down, with an air of sparseness. "The rustling of falling trees" arouses the poet's feeling of "sad autumn", and the "rolling of the Yangtze River" arouses the poet's emotion about his life experience. "Boundless" and "Endless" make the "Xiao Xiao" and "Rolling" more vivid, which not only reminds people of the sound of falling wood and the turbulent shape of the Yangtze River, but also conveys the feeling that time is fleeting and ambitions are hard to achieve. . Through the melancholy and sad couplets, the author shows his superb writing power.
