Competition is the motive force and source of human social progress. It is indisputable that people treat everything in the world with a free and easy attitude towards life. Contention and non-contention contain great wisdom in life. Darwin's theory of evolution can be summarized in eight words: natural selection, survival of the fittest. In this world, it seems that no creature can escape the word "struggle" of the eight major famines throughout the ages. In order to survive, lions need to compete for food, and plants need to compete for sunlight, air and water. To develop, a race must compete with animals for territory and resources. Competition has become a necessary ability for living things to survive. Lao tze said again; "The second time is indisputable, so the world can't compete with it." Inconsistency is relative, which is the wisdom of survival and of course the highest state of struggle. Shenchuan and Vientiane Music are two water heater manufacturers with equal strength, both of which are important bosses in the industry. But the two companies did not fight to the death for the position of the industry leader, but in the middle of not making money, you promoted for me, I made a name for you, and finally * * * won. There is no doubt that it exists from the point of view that it is conducive to enterprise progress and social development. Fight or not, wisdom is in it. Confucius once said that different people have different opinions. Confucius once said, I don't argue with others, and it's not worth winning or losing. Contention and non-contention are not random choices, but seeking truth from facts and objectively analyzing the situation I am facing. Is it an indisputable choice or is it indifferent and free and easy? Liu and Kong Jinhui, two superstars in contemporary table tennis. They come from the same school, and at the same time, they put on the national shirt and compete for the championship medal in the world arena, because they know that going all out at this moment is the greatest respect for their old friends, and international doubles will not win the top spot, and they must overwhelm each other. Undoubtedly, it shows the competitive spirit of sports in China. Look at Zhang Zhidong, a famous minister in the late Qing Dynasty. He explored flowers in the imperial examination, but he was very depressed. He thinks he should be the best. In dealing with people and things, he once said that there are three indisputable things in life: one is not to compete with the laity for profit; Second, do not compete with the scribes for fame; Third, don't compete with meaningless people for leisure. Zhang Zhidong's contention and non-contention shows the great wisdom of life. Struggle is a life creed unwilling to lag behind, and it is a life realm of introversion and aloof, otherwise it will be dusty. Fight, don't mess, fight; Argument is not indulgence, timidity, or escape. Therefore, the wisdom lies in the struggle and non-struggle.
