What characteristics do the first two sentences of the two quatrains describe?

The water waves in the river, the white feathers of waterfowl, the green and red flowers on the mountain are in contrast, and you want to burn. I watched it again and again this spring. When is New Year's Eve? This is a landscape painting embedded in a frame. The paper is full of ink, and the painting is colorful and fascinating. The rippling river shows the beautiful scenery of white water birds skimming the river. Full of green is full of mountains and plains, and the flowers everywhere are extremely red, like a burning fire, very beautiful and brilliant. White bird feathers are lined with river walls, and blue and white set each other off; Green hills are lined with red flowers, and green and red compete. The word "Guo" makes the waterfowl whiter and whiter with the blue sediment of the river, and writes deeply and picturesque; And a word "desire" endows the flower with anthropomorphic dynamics and swaying. There are four poetic images of rivers, mountains, flowers and birds, which are depicted in four colors: green, green, red and white. The scene is fresh and pleasing to the eye. However, the poet's will is not here, and then, the pen road turns sharply and laments. "I saw it again this spring. When is the year of return? " The word "read through" in the sentence refers directly to the season of writing poetry. The scenery in late spring and early summer is not beautiful, but it is a pity that the years have passed and the return date is far away, which not only does not arouse the interest of playing, but evokes the sadness of wandering.
