Listen to me. What does this poem express?

In very hot summer, farmers are still working in the fields, and a lot of sweat drips into the soil. This is what the author wrote when he saw the farmers who had a very hard life farming in the fields. At that time, the weather was very hot, but farmers had to work in the sun and sweat a lot. He expressed the author's sympathy for the working people, praised their hard work and criticized the rulers at that time. Mainly expressed a few points. First, sympathize with the working people. In the hot summer, people feel very tired after walking a few steps, but the hard-working farmers have to work in the fields. It is conceivable that such hardships are difficult for many people to understand. And if they don't do this, they will have no source of livelihood, and they can't live without food, so this is also a helpless performance. Seeing this situation, the author is full of sympathy for them. I think their life is too hard, so do many farmers. Second, praise for the working people In the hot summer, these working people did not hide in the house to enjoy the cool, but also actively worked underground. Such a figure is very touching.
