What techniques are used in Huang's poems? Where are they?

It mainly adopts four rhetorical devices: analogy, exaggeration, metaphor and duality. Quote the original text of Ode to the Yellow River and mark the rhetoric place:

Ah, friend! With his heroism (personification),

Vilen in Asia; It shows the spirit of our nation: great and powerful! Here, we sing the Yellow River. I stood at the top of the mountain and watched the Yellow River roll eastward. The waves are rough, causing a big tide (exaggeration);

Turbid flow turns around and forms a nine-curve chain (which is dual to the above sentence "Worship with surging waves and set off outrageous waves"); Running from the foot of Kunlun Mountain to the edge of the Yellow Sea, splitting the Central Plains. The Yellow River is a sword, and "chopping" is a metaphor) is divided into two sides.

Ah! Yellow River! You are the cradle of our nation (metaphor)! Five thousand years of ancient culture originated from you;

In Ode to the Yellow River, the poet uses symbolism, ostensibly praising the Yellow River, but actually praising our nation, inspiring Chinese sons and daughters to be "great and strong" like the Yellow River and defending the Yellow River and China with heroism and strong determination. It shows the unruly blood of the Yellow River and the heroic spirit of the Chinese nation, and praises the majestic momentum and long history of the Yellow River.

Genre is ode, focusing on "ode", and structure is closely related to the first chapter of the group poem "Song of the Yellow River Boatman". In the second chapter "Ode to the Yellow River", the poet appeared as a singer of the times. Standing on the top of the mountain, he sang the Yellow River ode on behalf of the heroic sons and daughters of the motherland. He praised the Yellow River for its majestic and long history, and should follow its example and be as great and powerful as it.
