Dayan River-What's the artistic conception of my nanny's poems?

The poet wrote the poet's true feelings about the nanny completely truthfully. However, this poem is not about Dayan River: it has become a symbol, a symbol of the earth, a symbol of hardworking people in China, and a symbol of a great mother. Dayan River has no name. Dayan River is just a place name, where she was born. Dayan River is common. Her life is full of ordinary things, which is the silhouette of her miserable life. Her living space is the former residence of a "dead tile", a "ten-square-foot pawn garden", and there is only a "grave full of grass" after her death. Her life is a "black sauce bowl", a "sewing clothes torn by thorns for her son", and washing vegetables and cutting vegetables in the cold river. Her son and husband live a relatively stable life under her care. After her death, they lost these things, and they lived in the hail of bullets and the curse of the landlord. Her image is also the image of the working people connected with the land. They are all rooted in the earth and have the great qualities of workers.
