Leaves, boundless, swirl, rustling down; The flowing Yangtze River is surging and rolling forward. Zhuan Xu is a famous sentence throughout the ages. It is written about the solemn and bleak and vast scenery in autumn, which is scattered when you look up and down. "Boundless" magnified the appearance of fallen leaves, and "rustling" accelerated the speed of falling. While writing the scenery, I deeply expressed my feelings and conveyed the feeling that my youth is fleeting and my ambition is hard to pay. Its realm is magnificent, and its touch is not only limited to the sadness at the end of the year, but also reminds people of the disappearance and limitation of life and the infinity and eternity of the universe. Through the gloomy and sad dialogue, it shows the poet's superb brushwork and has the majestic momentum of "building a raft and walking on a banyan tree", which is praised as "unique in ancient and modern times" by the predecessors who "pay attention to the East".
