Debate contest, whether it is easier said than done, we know that it is easier said than done. I am a three-debater. Please help me think about some questions I asked each other.

First of all, you need to know the origin of these two. One is what the history books say, "It's hard to know what you can't do." Confucius Biography: "What you know is easier said than done. "One is Sun Yat-sen's suggestion. From the practice of bourgeois democratic revolution, I deeply feel that this traditional old theory can not only stimulate people's enterprising spirit, but also encourage a fear of peace." I don't know what I don't want to do, but I dare not do it if I know, so there is nothing to do in the world. "He believes that this is an important reason why modern China was weak and declined, and the revolutionary cause could not succeed. In order to get rid of this old traditional concept and inspire people's courage of "being fearless and willing to do things", Sun Yat-sen put forward the opposite proposition: "It is not difficult to do things, but it is only difficult to know", using ten things such as diet, money, composition, building, shipbuilding, city building, talking about rivers, electricity, chemistry and evolution theory as arguments, indicating that people had it long before they sought some scientific knowledge. Taking the American Revolution and Japan's Reform as examples, he further pointed out that "it is absolutely not difficult to do it" with the guidance of "true knowledge". Accordingly, he believes that as long as we can resolutely get rid of the superstition that "it is not difficult to know, but it is difficult to act" and strive to win the revolutionary victory, it will be "a piece of cake." "

You can find out ten examples put forward by Sun Yat-sen and ask some questions from the shanzhai problem. What's more, Sun Yat-sen's idea of "doing things easily despite difficulties" also has its limitations. It is better to explain these two sentences to him and put them into modern life and study.
