Quatrain is a main carrier of Tang poetry. Its characteristics mainly include the following aspects.
1. It is short in length. Use the fewest words to express or show the theme you want to express. Or simply say: intercept a section of the most prominent picture to express the author's intention.
For example, Wang Han's "Liang Ci":
The luminous cup of grape wine will prompt you to drink pipa immediately.
Don’t laugh when you are lying drunk on the battlefield. How many people have fought in ancient times.
2. The language is clear. It means that the expression of the poem should be clear so that people can understand it at a glance.
For example, Li Bai's "Quiet Night Thoughts":
The bright moonlight in front of the bed is suspected to be frost on the ground.
Look up at the bright moon and lower your head to think about your hometown. There is also He Zhizhang's "Book of Returning to Hometown":
When a young boy leaves home, his elder brother returns, but his local pronunciation remains unchanged and his hair on his temples fades.
Children don't recognize each other, and they smile and ask where the guests are from. Come everywhere.
3. The theme is ordinary. That is, the subject matter should be common, typical, universal, and rarely used. For example:
"Ode to the Willow" by He Zhizhang:
Jasper is made up into a tree as high as a tree, with thousands of green silk ribbons hanging down.
I don’t know who cuts out the thin leaves. The spring breeze in February is like scissors.
4. It means long-lasting meaning. That is to say, the poetry has a long lasting charm and long-lasting affection, which is the so-called singing and sighing three times, and the lingering sound is endless. This is actually a matter of technique and cultivation. Without that cultivation, it would be difficult for you to sing and sigh, let alone three sighs. Let's look at an example poem:
"Sending a Letter to the Twenty-Two Members of Qiu on an Autumn Night" by Wei Yingwu
Huaijun belongs to the autumn night, and he walks and sings about the cool sky.
The pine nuts are falling on the empty mountain, and the lonely people should not be sleeping.
