Which ancient poem does "the mountain can't understand Tongguan" come from?

From Tongguan, it is a poem written by Tan Sitong 14 years old, which is a seven-character quatrain. At that time, he worked in Gansu with his father and passed through Tongguan, Shaanxi. He was shocked by the magnificent scenery unique to the north and wrote this poem.

The whole poem is as follows:

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 it is not smooth to enter Tongguan Mountain.

The translation is as follows:

This young man, full of heroic spirit, rode up the Tongguan ancient road halfway up the mountain, looking at the river by the mountain, and on impulse, he went forward bravely. The crisp sound of hooves was blown away by the hunting west wind and flew into the rolling clouds. Probably from ancient times to the present, this magnificent Tongguan has been surrounded by white clouds and has never been cleared, has it?

Extended data:

Tongguan is located at the junction of Shaanxi, Shanxi and Henan provinces, with Huashan peaks in the south and Yuxi Plain in the east. The poet immediately entered the city and saw the Yellow River roaring from the northern plateau canyon, suddenly turning at the foot of the cliff and heading for the flat and vast Yuan Ye, but the momentum did not ease, as if the riverbed was still too tight.

The continuous peaks are not so eye-catching in Kanto. As soon as they entered Tongguan, they suddenly rose and soared, fighting for the odds and risks, lest they appear mediocre!

Naturally, the so-called "the river is too tied" and the mountains are too uneven, which are all induced by the majestic momentum of the Yellow River and Huashan Mountain in the poet's mind, reflecting the heroic and unrestrained passion of young poets and their desire to get rid of feudal shackles and pursue ideological emancipation, and completely in tune with the social trend of change and rising power in China at that time.

/kloc-at the end of 0/9th century, in the history of our country, it was an unprecedented era of national crisis and national spirit. Through Tan Sitong's romantic poems, we seem to hear the footsteps of a new era approaching rapidly.
