Example in life: A parent reprimanded his son, and your foreign language performance dropped again. Do you know the reason for falling behind? My son said, yes, I didn't study hard enough. Parents "chase after victory", now that you know the reason, what should you do? My son solemnly said that he would get up at 6 o'clock tomorrow to recite words and ensure that his grades were in the first place 10. However, the next morning, no matter how loudly the parents shouted, the middle school student continued to snore like thunder and refused to get up. "The truth is known", but "it is difficult to do". This is what we often say "easier said than done".

In his book, Dr. Sun Yat-sen explained the truth that it is easy to overcome difficulties and cited ten examples. These ten examples are: (1) Take diet as evidence: everyone does what he wants, and does it every day. But it is impossible for people who have not studied physiology to know the way, which is difficult to understand diet. However, everyone knows how to eat and drink, which is easy-you can do it without knowing. (2) Take the use of money as evidence: money is the medium of transactions, and everyone uses money every day. It's easy to use money, but what is the essence of the former? What's the role? How to produce and evolve? Not known to the general public. (3) Take composition as evidence: Everyone can write an article, which is easy to write, but people who don't know grammar or arts and sciences abound. (4) Take building a house as evidence: building a house on a building is not difficult, because it is easy to do, and unless it is profound and special, it is impossible to know the composition design. (5) Take shipbuilding as evidence: Zheng He did not have scientific knowledge of shipbuilding in Ming Dynasty, nor did he replace manual machinery, but he was able to build 64 large ships in fourteen months, which proved that shipbuilding was easy, but it was difficult to know the ship. (6) Based on fortification: The Great Wall of Wan Li could be built in Qin Dynasty without science, machinery and engineering, which proved the difficulty and ease of fortification. (7) Take Kaihe as evidence: Emperor Yang Di dug the Grand Canal with brute force, but he didn't understand the engineering principle, which proved that it was difficult to learn but easy to learn. (8) Take electricity as proof: the compass can be proved without any knowledge of electricity and magnetism; Similarly, many people use electricity, but few people know it, which proves the theory that it is easier said than done. (9) Take chemistry as evidence: China people have known how to make pottery and tofu for a long time. There are many chemical procedures in the production process, but they don't know why. (10) Take the theory of evolution as evidence: human beings have propagated and followed the reality of evolution for millions of years, but it was not until Darwin came out that they suddenly realized. Dr. Sun Yat-sen illustrates the reasons for going to Yi Zhinan by taking ten major events as examples from human historical events and ordinary people's life experiences. Whoever "knows" thoroughly will easily "go". Knowledge and action can promote each other. We must know by doing, and do better because of knowing, so strength and behavior are the most important.
