Catfish, an active fish, is nothing special. However, since some fishermen used it as a tool to ensure the survival of sardines in long-distance transportation, the role of catfish has been paid more and more attention. Sardines naturally like to be quiet and pursue stability. I don't have a clear understanding of the dangers I face, but I am very comfortable with my present life. Fishermen skillfully use the active function of catfish to ensure that sardines are alive, and also get the greatest benefit in the process. In Norway, fishermen catch sardines and often die before they can go on the market, and they always can't sell at a good price. So, someone put a catfish in the fish tank, and the catfish chased the sardines and saved their lives. This is the famous "catfish effect". From the "catfish effect", we can get the enlightenment that only competition can survive and develop. (Analysis) Competition is to break a dead state and introduce a new mechanism, and the "catfish effect" is to change the sluggish state of sardines and make them active, thus achieving the purpose of saving lives. From this perspective, the "catfish effect" is a competitive effect. The history of mankind can also be said to be a history of competition. The emergence, survival and development of human beings are all realized in competition. Darwin's theory of evolution said: "Natural selection, survival of the fittest". Human beings grow and develop in competition with nature. In this kind of competition, human beings have formed physiological and psychological characteristics, thus conquering nature more effectively. While human beings are competing with nature, there is also fierce competition among different ethnic groups, such as the Chinese, Aryan and Europa ethnic groups with a long history of civilization. It is precisely because of this competition that mankind has such a prosperous scene today. Imagine, if there is no such competition with heaven and man, I am afraid we will climb trees like apes and live a life of eating and drinking blood! Today, with the development of human civilization, competition plays a huge role. In the fierce political, military and economic competition, a country can truly stand in the world only by becoming a strong competitor. Those who fall behind in the competition will only be bullied. Once upon a time, we were amazed at the automobile market war between the United States and Japan, puzzled by the dazzling advertisements in the West, and even turned pale when it came to competition. It seems that competition is only the inevitable product of capitalism and is synonymous with conspiracy and meanness. Today, we finally introduced the competition mechanism. In enterprises, bidding and contracting, optimizing labor combination; Develop market economy and encourage free competition; Even the election of deputies to the National People's Congress (NPC) has reversed the situation of lacking only votes in the past, allowing candidates to run on stage. I remember a saying: "In Chicago, girls wearing high heels walk faster than mainland boys." But now, don't you see, people are in a hurry? Competition is the catalyst of modern civilization and the competition of the strong. To realize the dream of a strong country that the Chinese nation has dreamed of for many years, we must bravely go to the world and undergo the forging of competition. In China, an ancient country, people seem to be too "modest". When European and American countries became strong in the industrial revolution, we were still studying the old paper piles leisurely and sticking to the golden mean, while China, which failed in the competition with the West, suffered humiliation and bitterness. Now, the awakened China bravely opened the door to meet the test of competition. Reform and opening up have made China look like an old tree in spring, which has given it new vitality. Modern society is an information society, and competition is the main theme of social development. Like Rykov, if you are trapped in a trap, you will die of depression like a dull sardine. Let each of us bravely participate in the competition, only competition can survive and develop. !
