The central idea and poem of the ancient poem "A millet planted in spring"

This is a poem that exposes social injustice and sympathizes with farmers' sufferings, focusing on the cruel exploitation suffered by farmers in the old society. In the first and second sentences, "a drop in the spring and 10,000 kinds in the autumn harvest", the use of "spring planting" and "autumn harvest" can roughly describe farmers' labor. From "one millet" to "10,000 seeds", the scene of bumper harvest is vividly written.

The third sentence, "There are no idle fields in the four seas", even states that all the land in the country has been reclaimed, and there is no idle field. The semantics of this sentence and the first two sentences complement each other, thus showing a fruitful and fruitful scene everywhere. The working people have worked hard to create such great wealth. Is it reasonable to have plenty of food and clothing in a bumper harvest year?

Who knows that sentence is "that farmer still starved to death." This is really shocking! The word "Jude" is thought-provoking: who deprived farmers of the fruits of their labor and trapped them to death? The word "I still starved to death" profoundly exposed social injustice and condensed the poet's strong indignation and sincere sympathy.
