Li Shen series: primary school students must recite 8 ancient poems to show respect for farmers and hoe crops at noon, and sweat drops down the soil. Who knows that every grain of Chinese food is hard. Appreciating these two short poems in the Tang Dynasty, which is full of flowers, is not a masterpiece compared with those famous poems, but they are widely spread, known to women and children, and are constantly recited and tasted by people, which is not without reason. First of all, the contents of these two poems are the most familiar things that people often come into contact with. However, you don't really know what you are most familiar with. There are many things that you turn a blind eye to in your life. If someone tries to enlighten you, explain the essence, or point out some truth involved, you will feel very eye-catching and clear, thus deepening your understanding. This is why these two little poems have vitality. "A millet is planted in spring, and ten thousand seeds are harvested in autumn", which is probably familiar to everyone and well known. However, it is often difficult for poets to contact society and class and think about some problems. It occurred to the poet, however, that he saw the cruel reality that "farmers still starve to death" from the bumper harvest scene of "all over the world" This dial is surprisingly eye-catching, which naturally leaves a deep impression on people. Another example is "Chinese food on the plate", which people used to contact every day and eat every meal. However, no one thought of linking this grain with the sweat of farmers under the scorching sun. The poet keenly observed it and condensed it into a poem "Every grain is hard". This enlightens people and makes them think about the truth, so that those who don't know how to cherish food are deeply educated. Secondly, when the poet expounds the above contents, he does not talk and discuss in an empty way, but uses vivid images and profound contrast to expose problems and explain reasons, which makes people easy to accept and understand. Like the first three sentences of the first song, in general, they all use vivid images to summarize the hard work of farmers in the vast fields, such as spring planting and autumn harvest. All this hard work has brought a lot of food, so we can live, but the last sentence has turned to the fact that "farmers are still starving to death." In this way, the situation before and after is in sharp contrast, which causes readers to think about problems and draw conclusions from the comparison, which is much more profound and powerful than the author telling readers his views directly. Another example is the second song. In the first two sentences, the author didn't say how hard farmers worked in farming and how difficult it was for crops to grow. He just made an image rendering of the plot of farmers sweating under the scorching sun, which made people make this kind of hard work and hard taste more concrete, profound and real. Therefore, it is very convincing that the poet finally said in a rhetorical tone that "every grain of food is hard." In particular, comparing grain to drip sweat is really subtle and vivid. Finally, the language of the poems is popular and simple, and the syllables are harmonious and lively, catchy and easy to recite, which is also the reason why these two short poems have been circulated among the people for a long time.
