At the end of Qin Dynasty, Chen Sheng and Guangwu rose up. Although they didn't see the day of victory, they planted the seeds of resistance to tyranny. Soon after, all the heroes in the world, led by Liu Bang and Xiang Yu, overthrew the tyranny.
China revolutionary pioneers, including Dr. Sun Yat-sen, also sowed the seeds of revolution and eventually overthrew the feudal dynasty. Although he did not see the establishment of the new China when he died, he left a sentence: "The revolution has not been successful, and comrades still need to work hard."
There is also the research and development of China's nuclear weapons. At that time, under very difficult circumstances, "two bombs and one satellite" was successfully developed. Of course, it is impossible to use these nuclear weapons at once, but it is a seed that has laid the foundation for China's military position in the world today and deterred foreign enemies from invading easily, which has led to today's good economic development.
