What kind of poetry does Tongguan belong to?

The Yellow River is still too constrained to run on the vast Yuan Ye. To the west of Tongguan, the mountains are connected and the peaks are undulating. I don't know what plain tan is.

Finally, high clouds were gathering in the city, and the autumn wind blew away the sound of hooves.

The river is still too wild, and the mountain enters Tongguan to solve the injustice.

For a long time, the high clouds gathered at this majestic pass, and the autumn wind blew away the sound of horseshoes.

The surging Yellow River and the vast vilen are not stretched enough. Even after entering Tongguan from Huashan, I don't know what flatness is.
