What scenes are described in the first two couplets of "A Park in Tonglu to Friends" in Yangzhou Poetry?

A stop in Tonglu and a friend in Yangzhou is a five-character poem by Meng Haoran. At the beginning of the poem, there are two couplets describing the sights seen along the boat on a moonlit night: at dusk, there are sad apes crying in the mountains, the surging Cangjiang River, the leaves on both sides rustling in the rustling wind, and the moonlight is bleak, reflecting a lonely boat. The extreme loneliness in the poem is in sharp contrast with the author's sad and anxious mood.

From a berth in Tonglu to a friend in Yangzhou.

Tang Meng Hao ran

The mountain was dark when it saw it, and the darkness of the mountain flowed eastward, day and night.

The wind on both sides of the strait rustled the branches and leaves, and the moonlight reflected on the river, a boat on a river.

Jiande's scenery is good, but it's not my hometown. I still miss my old friends in Yangzhou.

Recalling those two lines of tears that I couldn't restrain, I looked at the west side of the west bank and sent sadness to Yangzhou.
