What thoughts and feelings did Jiang Ting's jathyapple express when reading his Farewell?

Exquisite without losing artistic conception. Although it is a farewell poem, there is not a word "farewell" throughout, and the feeling of parting overflows from the poem. The poem is mixed with scenes, and the four images of "river, pavilion, night and moon" are intertwined to form a heavy farewell picture. Although there is no mention of people in the four sentences, there are people in every sentence and there are feelings in the scene. The first two sentences are "the smoke cage is full of smoke." The moon is flying. The whole scenery is obviously smart and the artistic conception is natural and beautiful. The last two sentences are "lonely from the pavilion, cold at night." Friends went to the south with the moon, and their figures disappeared like smoke. There is only a lonely pavilion in front of me, only a cold night, and the poet himself hangs on the shadow, which is infinite emptiness. These two sentences really pushed the artistic conception of the whole poem to a climax and made the poet's heart complicated and subtle.

It seems that all poems are about scenery, but
