What does it mean that the world praises heroes but also regrets that they will fall into dust?

? It means that people like to praise the great achievements of the world, but heroes will eventually leave people.

? A hero has the ambition to soar into the clouds, the power to swallow up mountains and rivers, the strength of nine states in his belly, and the mind of the whole world! Carry justice on your shoulders, save the people from water and fire, and relieve the people from hanging upside down. The dialectical truth of "Heroes create times, times create heroes" is inseparable from the two words "country" and "people". "Zai Jing Tang Ji·Min Shuo": "When the country is prosperous, thieves will follow the heroes to perform meritorious service; when the country is defeated, the officials will be like the scoundrels and ignore the law." The purpose of the article is related to this spirit. A hero has the ability to despise everything and the aura of being arrogant. The world not only respects him, but also is elusive. In ancient and modern times, at home and abroad, heroes are as numerous as the stars in the sky. However, the most special ones are very few, and the ultimate perfect ones are nowhere to be seen. This is because no one has met the above requirements. No matter how big the universe is, no one is immortal. However, if there is such a person, the sum of all lives can achieve eternal prosperity. When the country is in crisis, there are always some people who come forward to serve the country. Such people are called heroes. The heroic spirit of heaven and earth remains awe-inspiring for thousands of years. During the peaceful reform period of modern national rejuvenation, a large number of national heroes and heroic groups also emerged, such as Kang Youwei, Liang Qichao, Sun Yat-sen, He Ziyuan, Tan Kah Kee, Qian Xuesen, Deng Jiaxian, Tongmenghui, and patriotic overseas Chinese groups. Whether workers, farmers, intellectuals, soldiers, businessmen, or overseas Chinese, a large number of national heroes have emerged among them. They have devoted themselves selflessly and without regrets to the independence and freedom, interests and security, dignity and honor of the Chinese nation.
