The Creation Background and Appreciation Expression of Liu Yin's Into the Mountain

The first three chapters of this poem describe the beautiful scenery in the mountains, spider silk in the grass and autumn insects, which can't tell the difference between east and west, north and south, and express the love for the great mountains and rivers of the motherland. In the fourth chapter, I explained the meaning of "climbing the mountain" in the first three chapters and expressed the poet's endless grief over the fall of mountains and rivers. The way of background writing is to have feelings in the scenery.
