(soil, attached to the earth, is soil; Ups and downs in space are dust. Write an 8-word composition based on this poem. Urgent!

soil and dust the history of mankind has been slowly more than 5, years, and how many hardships and sufferings have it experienced. In this long process, there are always people who overcome this hardship and suffering for the benefit of the group and become "fertile soil" to nourish human growth; However, some people, regardless of the overall situation, bring disasters to the group and become "dust" to curb human development. Those "fertile soil" are immortal, and those "dust and sand" are notorious for thousands of years! //The real "fertile soil" is always those who devote their lives to the well-being of others. Li Shizhen, a famous medical scientist in ancient China, traveled all over China for the sake of people's health, and wrote Compendium of Materia Medica, which has been circulated through the ages, making indelible contributions to human medical research; Zhang Zhongjing, a famous physician in ancient China, was busy treating patients all day and wrote Treatise on Febrile Diseases with great love, which laid the foundation of traditional Chinese medicine and saved countless people who were tortured by illness! Their efforts and sweat have become the guarantee of people's longevity, and they have become fertile soil, dedicated and great throughout the ages! //The real "fertile soil" is always those who petition for the people and shed blood. Mao Zedong, a generation of eagles, created his own democratic Republic for China people with his full wisdom! In Zhou Enlai, the teenager decided to "study for the rise of China". For China and the people, he has been busy and dedicated all his life, so that China people can finally stand proudly among the nations of the world! Deng Xiaoping, a great man of the century who is "the great son of China people" and "deeply loves the motherland and people", overcame many obstacles and really made China people embark on the road to a well-off life! Together, they have created a new China, and they have become fertile ground for the growth of a new China, making her prosperous and powerful! //"Scattered mud grinds into dust and turns into spring mud to protect flowers" is a portrayal of great people, who always struggle for the people all their lives; On the contrary, people who deviate from the people and harm their interests to "feed" themselves often turn into dark sandstorms and bring disaster to the people. //Hitler, who was once called a "devil", did not hesitate to create terror and hatred in order to satisfy his distorted ambition, and how many branches, leaves and blood were lost in the "people's tree"! This disaster has already surpassed death. It is the sudden extinction of the light of human nature, which has cast a deep darkness on history. Yuan Shikai, a treacherous villain, stole the fruits of the Revolution of 1911 that countless revolutionaries exchanged their lives for, but he was so ridiculous and pathetic that he deviated from the people and history and was called the emperor! As a result, the farce ended in a few days, and soon he died of depression. He was a sinner of history for his own gain, which made people suffer disappointment and pain. He was a hateful pile of dust. //fertile soil and dust and sand, greatness and sin, have the same origin, but different essence. The wheel of history keeps rolling, fertile soil paves the way for him, and dust and sand lead him astray. How do you and I, who are of the same origin and as human beings, make a choice?//I hope it's not dust!
