First of all, I want to point out some mistakes made by my opponent. First, another debater just talked about the method, saying that it is really wise for Gong Yu to move mountains with time and effort, while moving is easy to avoid difficulties. However, this does not solve the fundamental problem. What we are talking about is a method to fundamentally solve the problem and change the philosophical quantity into qualitative change. Second, I don't understand how long it will take to move the mountain and how difficult the work is. If we are all afraid in the face of difficulties, then the modernization of China needs the efforts of several generations, and the difficulties and obstacles are too great. Should we give up? Gong Yu moved mountains, on the basis of facing up to contradictions, and made contributions to changing the backward appearance of his hometown. In the process of moving mountains, it has a great spiritual effect. The spirit of moving mountains has played a great role in promoting the development of the Chinese nation. Throughout history, the Chinese nation has experienced many crises. In this do or die, it is this spirit of struggle and persistence that has maintained the survival of the nation and changed its destiny. Chairman Mao warmly praised the spirit of the foolish old man in the article "The foolish old man moves mountains". Its spirit inspires people to overthrow the three mountains and build a new China. History and people will never forget that "learning from fools to move mountains and build a beautiful motherland" resounded through the land of China in the 1960s, which greatly promoted the socialist construction of the motherland at that time! Without the spirit of foolish old man moving mountains, there would be no motherland today, and without the spirit of foolish old man moving mountains, we would have no bright future. Today, in the process of socialist modernization, we will inevitably encounter many difficulties. Faced with these problems, should we just avoid them, as other debaters have said? Isn't such a big western China a no-man's land? In today's society, corruption is prevalent, and immoral behaviors such as gambling are temporarily exaggerated. Faced with these problems, should we ignore them and let the social atmosphere continue to deteriorate? The answers to these questions are all negative. Everyone in China will not be indifferent to these problems. Only when we are stupid enough to move mountains and rivers, not afraid of difficulties and stick to the end can we solve these problems and have a bright future. Now my speech is coming to an end and the whole debate has come to an end, but we still have a long way to go. When we encounter difficulties, the audience and other debaters present will face these problems with us and solve them with the spirit and boldness of a fool moving mountains. After conquering the high mountains, we will have a bright and beautiful tomorrow.
