Look at the Red Wall Fu before the full text, and talk about how the author's thoughts and feelings have changed.

The scenery of "Red Cliff Fu" is quite different. After explaining the time, place, people and activities of the night tour, the author wrote the scenery. The poet is rowing on the river. It is early autumn, and the gentle autumn wind blows slowly, fiddling with the poet's skirt and hair, blowing away the annoying summer heat, and the river is quiet and calm. The poet writes a letter with a pen, and his mood is relaxed and natural. After the poet wrote a poem about drinking with the guests, he wrote about the river view of Chibi after sunrise: white fog floating on the wide river, under the bright autumn moon, the water and sky on the river are connected, crystal clear. The river scenery written by the poet under the autumn night and the moonlit night reflects his clear inner world, which is free and easy, while the scenery of Chibi written in Fu on the Red Wall is ethereal, bright and soft, which reflects the poet's carefree and free mood.
