Through history, we understand this truth We must vigorously develop the economy, increase the income of the national economy and raise the total output value of the national economy. Only in this way can we upgrade China's status, make our country stronger and have more say, and let China, the lion, stand in the forest of the world and never let the history of modern humiliation repeat itself. The modern history of China is simply a history of humiliation. I believe that every descendant of the Chinese people will never forget a truth: lagging behind will be beaten, and lagging behind will be invaded by others. If we want to avoid being insulted and bullied by others, we must make ourselves strong. How can we become strong? First of all, we must be economically strong. There is a saying: "the economic base determines the superstructure." You will be beaten if you fall behind. If you want to stand among the nations of the world, you must make up your mind to strengthen yourself. During the Opium War, China was backward in weapons, science and technology, economy and, most fundamentally, social system. To strive for self-improvement, we must transform society, develop social productive forces and strengthen national defense. How can we develop the country and strengthen national defense? Only when our country's economy is rich can we develop science and technology, culture, national defense, manufacturing and so on. Therefore, the economy played an important role in the modern history of China. Economy determines politics and culture, and what kind of economy will produce corresponding politics and culture; On the contrary, politics and culture react on the economy. Therefore, China's economy plays an important role in world economic development.
