Why is Chengdu called the land of abundance?

In ancient times, because people's productivity was relatively backward, they left a bad impression on some places they had never set foot in. People in ancient times had such an understanding of Sichuan, and because there were many insects in the Woods of ancient Sichuan, no one dared to approach it, so it gave people an impression of being uneducated and wild. Chengdu is called the land of abundance because its floods have been controlled, and it has become a rich place with the reputation of a land of abundance.

First, ancient people would avoid places they had never explored, because they were afraid to enter unknown areas easily. In ancient times, Sichuan was an unknown territory. Although there is a trade route in Sichuan Province, there are still many unknown lands. Naturally, Sichuan has left a bad impression in people's minds. In addition, there are frequent floods in Chengdu, and no one is going to cure them, so they avoid Sichuan and Chengdu.

Second, the turning point of Dujiangyan occurred after Qin unified the six countries. After Qin Shihuang unified the six countries, the world was greatly shaken. For an underdeveloped place like Sichuan, Qin Shihuang was determined to win. He sent Li Bing to control the flood in Chengdu. After Li Bing arrived in Chengdu, he built Dujiangyan, a water conservancy project. The construction of Dujiangyan is a historic and great project. The flood was controlled, and Chengdu became a land of plenty.

Third, the battleground for military strategists Since the floods in Chengdu were well controlled, Chengdu has become a battleground for military strategists. Whoever owns Chengdu is equivalent to owning an inexhaustible granary. When two-thirds of the world, Chengdu is the territory of Shu Han. It was because of occupying a place like Chengdu that Shu Han had enough confidence to compete with Cao Cao and Wu Dong for the unification of the world at that time. Now Chengdu is still a land of abundance, and its annual grain output is very large, occupying a very important position on the whole map.
