On this day, 69 years ago, August 30, 1956 (July 25, 1956, the lunar calendar), Mao Zedong discussed "ball origin". On August 30, 1956, Mao Zedong delivered a speech "Strengthening Party Unity and Inheriting the Party's Tradition" at the preparatory meeting of the Eighth National People's Congress of the Communist Party of China, calling for uniting all forces that can be united and doing a good job in construction, otherwise he would be expelled from the "ball club." Mao Zedong said that China is a country with a population of 600 million, and there is only one on earth. In the past, people looked down on us because we had no contribution. Steel only has hundreds of thousands of tons a year. In 1956, it was more than 4 million tons. In 1957, it could exceed 5 million tons. The second five-year plan exceeded 10 million tons; the third five-year plan may exceed 20 million tons. The United States is the most powerful capitalist country in the world. It was founded only 180 years ago, and its steel production was only 4 million tons 60 years ago. If there are another 50 or 60 years, we should completely catch up with it. This is a responsibility. "You have so many people, you have such a big place, so rich in resources, and I heard that you have built socialism, which is said to have advantages. As a result, you have been building it for fifty or sixty years and still cannot surpass the United States. What are you like? Then you will be expelled from the face of the earth!"
