The whole article revolves around the word "bitterness", which is written from the beginning of the year to the end of the year in the order of seasons, from farming and sericulture to hunting and ice cutting, reflecting the multi-level working face and high-intensity labor all year round. Between the lines are sadness and pain, as if telling a heavy history. But what is worth knowing is that this poem shows a certain sober class consciousness while complaining. "Women are sad." ""Take a fox for your son's sake. " "Dedication to the public" and "meritorious service in the palace" all show the slaves' suspicion and dark hatred of the nobles for eating without work and bullying. When expressing class oppression, the poem also uses comparative descriptions, such as slaves working hard, but "the fields are full of joy" and suffering. Slaves have no clothes and no brown, but they are "for their sons" and "for their sons", the contrast between cold and warm; This description, such as the contrast between less and more, consciously reveals the inequality of class oppression.
In addition, the poem is good at grasping the characteristics of various phenology to express the evolution of festivals, which makes the whole poem full of natural scenery and strong local flavor, especially in the fifth chapter: "In May, pheasant wings, in June, it is in the wild, in August, in the house, in September and October, crickets enter my bed", and vividly expresses the seasons with the chirping of insects and the migration of crickets. However, it makes us feel that the weather is getting colder every day, so that it is chilly. This technique is widely used in July, and another example is: "Flowers bloom the day before, but the day after", which shows that the season gets cold with the increase of wind, and it is also very vivid.
