What thoughts and feelings did the poet express in Liu Jingwen's Journey?

The poem "Walking on the Mountain" describes the scenery seen on foot in autumn, showing a moving autumn color map of mountains, mountains, people, white clouds and red leaves, forming a harmonious and unified picture, and showing the prosperity and lofty thoughts of the author Gao Huai.

The poem "To Liu Jingwen" expresses the author's broad mind, exhorts and supports friends in the same predicament, and expresses his ambition with lofty artistic conception.

With the scenery as the background and the silence of autumn night accompanied by the sound of leaves and the wind, the poem "What I See in a Night Book" compares the sadness of being in a foreign land with the music scenes preached by children at night by means of contrast.

The original "hiking":

In the distance, there are cold mountains, oblique stone paths and people in the depths of white clouds.

Stop and sit in the maple forest late, and the frost leaves are red in February flowers.

Walking on the Mountain is a poem by Du Mu, a poet in the Tang Dynasty. The author controls the scene with emotion, quickly and accurately captures the image that can reflect the natural beauty, and integrates his own emotions into it, so that the emotional beauty and the natural beauty are integrated and the scene is blended. The whole poem is novel in conception and exquisite in layout. It absorbs gorgeous autumn colors in the bleak autumn wind, competing with spring, pleasing to the eye and making people more energetic.

The original "To Liu Jingwen":

The lotus flower withered, so did the lotus leaf holding the rain, and only the branches of chrysanthemum stood proudly against the frost.

You must remember the best scenery in a year, which is in the late autumn and early winter of orange and green.

To Liu Jingwen is a seven-character quatrain written by Su Shi, a writer in the Northern Song Dynasty. In the first half, he said, "The lotus is exhausted", and he should be proud of the ice and snow. In the second half, he encouraged his friends to be optimistic and not depressed through Orange Green.

The original "night book can see":

The rustling leaves send the cold sound, and the autumn wind moves the guests on the river.

I know that children choose to promote weaving, and a lamp fell on the fence at night.

What I saw in the Night Book is a seven-character ancient poem written by Ye Shaoweng, a poet in the Southern Song Dynasty. One or two lines in the poem describe the scenery, and the feeling of falling and lonely is set off more desolately by fallen leaves, rustling autumn wind and chill. Write three or four sentences about children catching crickets at night, with high interest, skillfully comparing sadness and showing loneliness and helplessness living in other places.
