There are many factors that affect people's vision, in addition to their own knowledge, there are also external social productive forces, so in the feudal period due to the limitation of productivity, so the whole society is also full of feudal superstitious ideas.
To this day, we are educated in materialism, so we can also analyze dialectically and rationally some of the words and ideas left to us by the ancients.
In Darwin's theory of evolution, we can know that everything in the world is constantly evolving, and the original feudal thinking that "God created all things" has been completely overturned. Therefore, some superstitious ideas that were caused by the influence of social productive forces in the feudal period were also completely overthrown.
In the folk, snakes have a lofty status, and are even called earth dragons, so how long can snakes live? Legend has it that the great snake of more than five hundred years can transform into a jiao, what is the "Yangtze River Walking Jiao"?
Everything in the world has a beginning and an end of life, so there is no immortal thing at all, so is there a great snake in this world that really has a lifespan of more than five hundred years? The snakes we see today are a type of biodiversity on earth, and snakes are also an important part of ensuring ecological balance. The dragon was originally the good wish of the working people in ancient times, so it is also a beautiful idea that the snake can transform into a dragon and eventually transform into a dragon.
Affected by genes, so the lifespan of snakes is also unequal, such as small snakes generally live about 4 to 5 years, longer-lived snakes, such as Burmese pythons, due to their large size, and no natural enemies, so their lifespan can reach about 30 years.
Under normal circumstances, the lifespan of wild snakes will be shorter than the lifespan of raised snakes, because wild snakes will be disturbed by natural enemies and the influence of diet and external environment, and the raised snakes can be described as "life worry-free", so the life of raised snakes is relatively long.
Although some snakes can live to more than thirty years old, but due to various factors that lead to the real survival of thirty years, longevity of snakes is very small, so there is still a certain distance from the ancient working people legend of the snake can live 500 years, so "snake 500 years into a dragon, and the dragon into a dragon for a thousand years" is just a good wish.
So since Jiao is just a beautiful imagination of the ancient working people, what is the Yangtze River Jiao? Because the ancients were under the influence of feudal superstitious ideas, they were convinced of the Yangtze River Jiaojiao, and even in order to deal with the dragon, they would hang a sword under the bridge to suppress the dragon.
Ancient people believe that the dragon can withstand the water, and the dragon will appear flood, because the feudal period is in the agricultural economy, so the emergence of the flood will also bring about the corresponding flood disaster, will make the people displaced, so the ancients will unswervingly believe in the Yangtze River after the phenomenon of jiao, to hang a sword to deal with the strange dragon.
Floods can occur near the Yangtze River Basin, in fact, it has nothing to do with Jiaolong, because the geographical location of the Yangtze River Basin leads to a relatively large amount of precipitation every year, and the rain period is also very concentrated, so the probability of flood outbreak is also very large. The ancient working people were affected by the productive forces, so there was no solution to the emergence of floods, and they also did not understand why there were floods only near the Yangtze River Basin, so they one-sidedly believed that this was a jiao, so they would make some superstitious behaviors.
Moreover, the upper and lower reaches of the Yangtze River Basin are extremely uneven due to the huge difference in terrain, so the water flow is turbulent, so the power generated after the outbreak of flood disasters is also extremely great, and the rumbling sound can be heard from a distance, so it will lead to misunderstanding among the ancient working people.
Limited by the impact of social productivity, there was no good solution in the face of flood disasters in ancient times, but now we have come to a new era, and the Three Gorges Dam has been built in the Yangtze River Basin, so we can treat flood disasters scientifically and rationally, and we can also ensure the safety of people's lives and property to the greatest extent.
Summary: Looking at the ancient working people from our current point of view, hanging a sword above the bridge, this is feudal superstition, but this is the common thinking of the people caused by the social productive forces at that time, and perhaps this is also the best and most effective solution that society thought at that time, so we should treat all this rationally and dialectically.
With the idea of ecological environmental protection more and more deeply, so most people have joined the ranks of protecting the environment, and now under the premise that the ecological environment headquarters is getting better, we can also see the traces of snakes within the scope of human activities. But this can not be the reason for human beings to wantonly kill snakes, although the snake is only a small link in nature, but human beings are also the link to maintain the natural ecological environment, human beings and natural creatures are equal relations, so the protection of natural creatures is also the protection of human beings themselves.
