First of all, I think there are two aspects of obscurity. First, the hazy environment is the first two sentences of each chapter of Jiaxu: Jiaxu is pale and the white dew is frost. Jia Jian grew up, and the Millennium was not beautiful.
Second, the image of "Iraqis" is very hazy, but the surrounding environment makes the image of Iraqis hazy, and its unpredictable position, as the poem says:
The so-called Iraqis are on the water side. ~ ~ ten thousand is in the middle of the water.
The so-called Iraqis are in the water.
The so-called Iraqis are in the water.
The so-called Iraqis are here and there, and their whereabouts are uncertain. The protagonist can't know his true face, so he can only search hard. Therefore, it adds a little mystery and hazy beauty to the Iraqi people, and also gives the whole poem a hazy feature.
I hope it helps you!
