What does Liu Yuxi's Langtaosha (VII) mean?

Moral: In August, the sound of waves is like Ma Benteng's roar. Tens of feet of waves rush to the rocks on the shore and are knocked back. In a blink of an eye, I retreated to the intersection of rivers and seas and returned to the sea. The sand it rolls up is like a pile of snow in the sun.

From Nine Poems of Langtaosha by Liu Yuxi, a writer in the Tang Dynasty: In August, the waves roared, and the head was several feet high and touched the mountain. In a blink of an eye, I arrived at Haimen, and the rolled sand was like a snowdrift.

This is the seventh poem in the series "Langtaosha", which is about the Qiantang River and Lake on August 18th. Qiantang River, also known as Zhejiang. The mouth of the river is trumpet-shaped and the tide flows backwards, forming the famous qiantang bore. On August 18 every summer, Qiantang River is the most spectacular scenic spot in Haining. At high tide, on the tidal wall, the waves are rough and Malik is rushing, which has become a natural wonder through the ages.

Creative background:

Since the Anshi Rebellion in the Tang Dynasty, the momentum has declined. Governors are independent, eunuchs are authoritarian. When talented people are released and angered, resentful works are produced. After Liu Yuxi was transferred from Beijing official to local official, he also wrote famous works, such as Nine Poems of Langtaosha. This group of poems should be Liu Yuxi's later works, not created at one time and one place.

According to the Yellow River, Luoshui, Bianshui, Qinghuai, Nautilus Island, Zhuo Jinjiang, etc. Poems, or works for activities in Kuizhou, Hezhou and Luoyang, were later compiled into a group. Some scholars believe that this group of poems was written in the late Kuizhou period, that is, in the spring of the second year of Changqing (AD 822).

Appreciate:

The poet's writing perspective changed from folk custom to natural scenery. Liu Yuxi is waiting in a remote place. He can actively adjust his inner contradictions with the help of the power of nature. His mind broadened, his mood became optimistic and his poetry became bold. Poets also want to shorten the exile time as soon as possible, but they never bow to eunuchs. He Chao, a man of A Qing Dynasty, said that "a dream can be described as knowing how to go forward but not how to go back", which has some truth.
