Poetry about the use of contrast or symbolism.

Contrast is a rhetorical device, which highlights a main thing with one or more opposite things. Things that play a comparative role are in the position of opposition and contrast, and their role is the main thing or aspect.

For example, in the Northern and Southern Dynasties, Wang Ji, a poet in the Southern Dynasties, wrote Poems of Going into Evil Flow.

What's average? Empty water. The afterglow of the sunset rises from the distant mountains, and the sun shines on the winding water.

The cicadas are singing, and the Woods are particularly quiet; The singing of birds in the mountains is more beautiful than usual. This place has given me a hermit's heart. I'm tired of my official career but I'm not retired and sad.

Use cicadas and birds to set off the secluded forest.

Another example is Li Bai's "Xuanzhou Xie Tiao Building Farewell to Uncle Shu Yun"

I had to leave Potter and me since yesterday. It hurts my heart even more today.

Autumn geese are escorted by Changfeng, and I treat them in this villa and drink my wine. The bones of great writers are all your brushes. In Tianyuan, I grew up beside you, Xiao Xie.

We all yearn for the distance and want to go to the blue sky to embrace the bright moon. But since the water is still flowing, although we cut it with a sword and raise your cup to drown your sorrow.

Since the world can't satisfy our desire, I will loosen my hair and get on a fishing boat tomorrow.

People who abandon me, people who confuse my heart, and people who draw a sword and cut off water all use comparative methods to contrast the author's worries about life and the world.

For example, Liu Yuxi's poem Wuyi Lane in the Tang Dynasty:

There are some weeds blooming by the Suzaku Bridge, and there is only sunset at the corner of Wuyi Lane. Swallows under the eaves of Wang Dao and Xie An have now flown into the homes of ordinary people.

Describe the scenery to compare the vicissitudes of history with the changes in world space.

For example, in Li Shen's Sympathy for Farmers, weeding is done at noon, and sweat drips on the soil. Who knows that every grain of Chinese food is hard?

Use labor to set off extravagance and waste.

For example, Su Shi's "Jiangchengzi Mizhou Hunting"

I said juvenile madness, which led to yellow on the left and pale on the right. Golden hat, mink and fur, thousands of riding rolls and leveling posts.

If you want to report the whole city to the prefect, you will see Sun Lang.

It doesn't matter if the chest is still open after drinking wine and the temples are slightly frosted. Hold a festival in the clouds, when to send the phoenix hall.

I will make my strength as full as the full moon, full as the full moon, heading northwest and shooting at the team in West Xia Jun.

Use heroic writing to set off your own non-revenge, and use allusions to set off your feelings of being able to do things for the country but helpless.

Such as the Tang Dynasty Wang Changling's "Out of the Plug"

During the Qin Dynasty, the moon was in the Han Pass, and the Long March did not return. Longcheng flew in, and Huma did not teach Yinshan.

Use metaphors and allusions to compare the desolation of frontier fortress with the sadness brought by war.

Another example is Li Qingzhao's poem "Adding Words and Picking Mulberries"

Who planted banana trees in front of the window, the atrium is full of shade. Yin fills the heart, leaves warm the heart, and the volume is relaxed and affectionate.

Sad pillow night rain, a little light rain. A little rain, worried about hurting northerners, not used to listening.

This kind of banana and northerners are not used to listening to the rain to contrast their yearning for their hometown and their sadness about the destruction and displacement of the country.
