"Wild Grass" is a famous early prose by Xia Yan. In "Weeds", the author expresses his contempt for the weight of dark reality and his trust in the power of the people through the praise and affirmation of seeds, weeds and vitality. This article reveals a truth: the power of the people (weeds) is invincible. The author's purpose is to enlighten people's thinking, so he does not put much effort into lyricism, and mainly uses images to show a philosophy. The method adopted is a combination of narrative and discussion. Start by asking the question: "What is the most powerful thing in the world?" Then break into the topic and use special and general examples to answer this question, showing that grass and seeds are the most powerful in the world. Finally, it is pointed out that the reason why grass has power lies in its two outstanding characteristics: first, it uses life as the source of strength, it is persevering, flexible and stretchable, "resisting for a long time" and will never give up until it achieves its goal; second, it takes everything into consideration Difficulties and setbacks are regarded as exercises for oneself, and one should never be pessimistic or sigh. If we think about the connection between the life force of weeds and the political background of the time through words such as "long-term resistance war", it is not difficult to see why the author calls for weeds and the life force.
