How did Qin's western development turn Shu County into a land of abundance?

In 316 BC, in the main hall of Xianyang, the capital of the Qin State, General Sima Cuo and Prime Minister Zhang Yi had a disagreement. They started a fierce debate on whether to attack the ancient Shu Kingdom first, a battle that affected Chinese history. Decisions are about to be made. King Qin Huiwen in the movie and TV series Zhang Yi believed that ancient Shu was a remote and barbaric country in the west, not enough to establish a hegemony, and it was not suitable to waste people and money to attack it. However, Sima Cuo believed that destroying the ancient Shu would be as easy as flipping the palm of his hand. Seizing its land would be enough to expand the country, and seizing its wealth would be enough to enrich the people. If the country of Shu was occupied, it could also be attacked along the river to attack Chu. King Qin Huiwen followed Sima Cuo's advice and sent Sima Cuo and Zhang Yi to send troops to destroy the ancient Shu Kingdom, and also destroyed the Ba and Ju Kingdoms. The land of Bashu and the central and western parts of Han were integrated into the territory of Qin. According to historical records, since Shu belonged to Qin, Qin became stronger and richer, and despised the princes. Sima Cuo was an outstanding military strategist. With his keen vision, he discovered the energy contained in Bashu, a geomantic treasure land, which was of great significance. A large-scale development of Bashu land is quietly underway. Sima Cuo in the film and television drama The Shu region has unique innate conditions. First of all, agriculture, iron ore, and salt industries are developed, especially the flat Chengdu Plain, which has fertile land and is very suitable for the development of agriculture. Secondly, the land of Shu has been managed and developed for at least a thousand years by the Cancong clan, the Baiguan clan, the Yufu clan, the Du Yu clan, and the Kaiming clan of the ancient Shu kingdom. According to "Huayang Guozhi", there are records of the ancient Shu Kingdom moving its capital several times. The Du Yu family moved its capital to Pi (Pidu District, Chengdu) and Qushangcheng (today's Shuangliu District, Chengdu). The ninth generation of the Kaiming family moved to Chengdu. Now archeology has discovered ancient Shu ruins such as Sanxingdui and Jinsha. The Sanxingdui ruins are located in Guanghan City, and the Jinsha ruins are located in Qingyang District, Chengdu. These urban agglomerations had been managed and developed in the ancient Shu Kingdom, which made it easier for the subsequent "Qin State's Great Development of Shu Land". Qin Huiwen established Shu County in Shu Land and appointed Zhang Ruo as the first Shu County Governor, thus starting the Shu County. The county was greatly developed. After Zhang Ruo took office, he discovered that although the Chengdu plains were fertile, the minority tribes in the western mountainous areas were very strong and faced tremendous pressure for survival. The sparse population was a barrier to the development of Shu County, so King Qin Huiwen moved 10,000 households. The advantage of the Qin people going to enrich the Shu area was that the people from the Central Plains brought advanced tools and technologies, which enabled the further development of agriculture, salt industry, and iron industry. Zhang Ruo also built Chengdu City, Pic City, and Xianyang City in the Shu area, imitating Xianyang. The three cities of Linqiong, including Picheng and Linqiong, defended Chengdu from the ethnic minority tribes from the northwest and southwest mountainous areas. At the same time, they established supporting Yanguan, Tieguan, and Shiguan cities, and soon established Chengdu as a commercial powerhouse. The city turned Shu County into a large granary, and the grain, grass, and iron resources produced were continuously transported to the Central Plains to support the expansion of the Qin State. Let's see, Sima Cuo's strategy and Zhang Ruo's management played a great role. In 280 BC, during the reign of King Zhaoxiang of Qin, Sima Cuo set out from Shu County, sent 10,000 ships of rice, and led 100,000 troops to capture Qianzhong County of Chu State. If there was no support from Shu County, how could he provide food and people? In 277 BC, Sima Cuo and Zhang Ruo followed the river to capture Bajun and other places in Chu State, realizing Sima Cuo's strategic idea of ​​destroying Shu and gaining Chu. From 316 BC to 277 BC, Qin conquered Shu. It only took 39 years for the Qin State to form a counter-encirclement trend against the Chu State. After the Qin State achieved such a brilliant victory, King Qin Zhaoxiang realized that Shu County was a geomantic treasure, so he sent Li Bing as the second governor of Shu County, mainly to manage the Minjiang River. Floods. As we all know, Li Bing was a famous water conservancy expert during the Warring States Period. He built the famous Dujiangyan Water Conservancy Project in Shu. Since ancient times, the Minjiang River has been severely flooded during the rainy season, sometimes flooding large areas of the Chengdu Plain. The water flowed away in vain, and the farmland could not be irrigated. So Li Bing opened up the Min River in today's Dujiangyan City, built a project, and diverted water into the present-day Baitiao River, Puyang River, Zouma River, etc. These rivers all flowed through the Chengdu Plain, so that the farmland could be irrigated. Dujiangyan Water Conservancy Project is a water conservancy project that integrates irrigation and flood control, so the Chengdu Plain has no longer suffered from droughts and floods. Dujiangyan Water Conservancy Project Li Bing is not only a water conservancy expert, but also a bridge expert. He built seven imitations of the Big Dipper around Chengdu. Bridge, the transportation in Chengdu has become very convenient and the four connections are developed. At the same time, Li Bing is also a master of salt production.

Although the salt industry in Shu County was developed at that time, the salt production technology was relatively backward. Li Bing created the "" method of digging wells, collecting brine and boiling salt," so Shu County had another economic lifeline. Li Bing can be called an ancient scientist. That's right. It was Li Bing's contribution that brought the development of Shu County to a higher level. According to historical records, "floods and droughts in Shu follow the people, and there is no famine" and "there are no famines, and the world is called Tianfu." This is also correct. This is the origin of the "Land of Abundance". After the Kingdom of Abundance, the support of food, salt and iron resources from the Kingdom of Abundance helped Qin Shihuang annex the six kingdoms and unify the world. So Qin Shihuang mobilized the population of Shangjun to enrich Shujun. During this migration, one of them was Zhuo Zhuo. The Zhuo family was moved to Linqiong. It was originally a blacksmith family in Zhao State. A few decades later, a man named Zhuo Wangsun came out of the Zhuo family. He started a business related to iron and became a wealthy man in Shu County. One side reflects that advanced iron smelting technology from the Central Plains was also brought to Shu County. According to the history of Qin Shihuang, from King Qin Huiwen to Qin Shihuang for nearly a hundred years, wealthy knights from the mainland continued to move to Shu County. ""The family has the advantage of salt and copper, the household is dedicated to the materials of the mountains and rivers, the people are well-off, and the wealth is the best", which solidifies the reputation of the land of abundance. From the foresight of Sima Cuo and the management of the first two prefects, Shu County passed through Qin Hui The migration and mobilization of several generations of Qin kings from King Qin Shihuang to the Qin Dynasty finally transformed the vast land of ancient Shu into a land of abundance. This also shows the profound wisdom and perseverance of the Chinese people since ancient times. Historical sources include "Warring States Policy" and "Historical Records of Qin".
