In ancient times, because people's productivity was relatively backward, they maintained a bad impression of some places they had never set foot in. This was how people in ancient times had such an understanding of Sichuan. And because the forests in Sichuan in ancient times were relatively lush, there were a lot of insects in the woods, and no one dared to get close. Therefore, it gave the impression of an uncultured, barbaric land. Chengdu is called the Land of Abundance because its floods have been controlled and it has become a place with fertile soil, earning it the reputation of the Land of Abundance. 1. Avoid places

People in ancient times avoided places that they had never explored because they did not dare to enter unknown areas easily. In ancient times, Sichuan was an unknown territory. Although there were trade roads passing through Sichuan Province, there was still a large area that was unknown. Sichuan naturally left its mark in people's hearts. A bad impression, coupled with the fact that floods occur frequently in the Chengdu area and no one goes to deal with them, so people avoid Chengdu, Sichuan and other places even more. 2. Dujiangyan

The turning point occurred after Qin unified the six countries. After Qin Shihuang unified the six countries, he had an aura of looking down on the world. Qin Shihuang was determined to win an undeveloped area like Sichuan, so he sent Li Bing to control the floods in Chengdu. After Li Bing arrived in Chengdu, he The water conservancy project Dujiangyan was built. The construction of Dujiangyan was a great historical event. The floods were controlled, and Chengdu became a rich land of fish and rice. In the history books of later generations, the word "Land of Abundance" was also used to describe Chengdu. 3. A battleground for military strategists

Since the floods in Chengdu were cured, Chengdu has become a battleground for military strategists. Whoever owns Chengdu is equivalent to owning an endless granary. At three points, Chengdu was the territory of the Shu Han. It was precisely because they occupied a place like Chengdu that the Shu Han had enough confidence to compete with Cao Cao and Soochow for the unification of the world. Today, Chengdu is still a land of abundance. Its annual grain output is very large and it occupies a very important position on the entire map.
