Which dynasty did this poem come from?

First, this poem is from Walking the Mountain, which is the work of Du Mu in the Tang Dynasty.

Second, the original poem:

The stone road winds to the cliff in the distance.

Where there are some white clouds, you can see some households.

I stopped the carriage and was fascinated by Fenglin.

The frosty autumn leaves are redder than the flowers in February.

Third, translation:

The rocky path is far from the top of the mountain, winding and crooked.

There are several in Baiyun.

I stopped the carriage only because I like the night view of Fenglin.

4. Du Mu (803 ~ 852), a poet in the Tang Dynasty, was born in Fan Chuan, Han nationality, Jingzhao Wannian (now Xi, Shaanxi). Born in a famous family, his grandfather Du You was a famous prime minister and historian in the middle Tang Dynasty. In his later years, Du Mu lived in Fan Chuan Villa in the south of Chang 'an, which was later called "Du Weizi" and "Du Fanchuan". Du Mu lived all his life in the late Tang Dynasty, when domestic troubles and foreign invasion deepened. He was concerned about state affairs since he was a child, and he cherished the ideal of saving the peril and restoring the prosperity of the Tang Dynasty. At the age of 23, he wrote A Gong Fang Fu, taking the abuse of power and extravagance in the Qin Dynasty as a warning, which sounded the alarm for the rulers of this dynasty. Together with Li Shangyin, they are called Du Xiaoli.
