Question: Why did China need to resettle people into the administrative territorial entity that contains Wuxi County?

full_context: Document 1: Sichuan: In the middle of the 17th century, the peasant rebel leader Zhang Xianzhong (1606–1646) from Yan'an, Shanxi Province, nicknamed Yellow Tiger, led his peasant troop from north China to the south, and conquered Sichuan. Upon capturing it, he declared himself emperor of the Daxi Dynasty (大西王朝). In response to the resistance from local elites, he massacred a large native population. As a result of the massacre as well as years of turmoil during the Ming-Qing transition, the population of Sichuan fell sharply, requiring a massive resettlement of people from the neighboring Huguang Province (modern Hubei and Hunan) and other provinces during the Qing dynasty.
Document 2: Qin Liangyu: In 1623, Qin Liangyu assisted Ming forces in suppressing the She-An Rebellion in Sichuan and Guizhou led by She Chongming (奢崇明) and An Bangyan (安邦彥). In the following year, her elder brother, Qin Minping (秦民屏), was killed in battle by An Bangyan's forces.
Document 3: Xu Guangda: Xu Guangda () (November 19, 1908 – June 3, 1969) was a People's Liberation Army general who was conferred the "Da Jiang" (Grand General) rank in 1955. His former name was Xu Dehua.
Document 4: Sichuan: From 1955 until 1997 Sichuan had been China's most populous province, hitting 100 million mark shortly after the 1982 census figure of 99,730,000. This changed in 1997 when the Sub-provincial city of Chongqing as well as the three surrounding prefectures of Fuling, Wanxian, and Qianjiang were split off into the new Chongqing Municipality. The new municipality was formed to spearhead China's effort to economically develop its western provinces, as well as to coordinate the resettlement of residents from the reservoir areas of the Three Gorges Dam project.
Document 5: Xiang Rong: Xiang Rong (; 18019August 1856) born in Wuxi County, Chongqing, was a general promoted from the rank of a foot soldier during the later years of the Qing dynasty (16361912). He was involved in early military operations against the Taiping Rebellion in Henan from 1850 onwards. From then he was a Senior Colonel，after one year the military promoted him be the "tidu" (提督) of Guangxi, even though he failed, he made the Taiping believers flee Guangxi.
Document 6: Sichuan: Sichuan was China's most populous province before Chongqing became a directly-controlled municipality; it is currently the fourth most populous, after Guangdong, Shandong and Henan. As of 1832, Sichuan was the most populous of the 18 provinces in China, with an estimated population at that time of 21 million. It was the third most populous sub-national entity in the world, after Uttar Pradesh, India and the Russian Soviet Federative Socialist Republic until 1991, when the Soviet Union was dissolved. It is also one of the only six to ever reach 100 million people (Uttar Pradesh, Russian RSFSR, Maharashtra, Sichuan, Bihar and Punjab). It is currently 10th.
Document 7: Sichuan: Sichuan has been historically known as the "Province of Abundance". It is one of the major agricultural production bases of China. Grain, including rice and wheat, is the major product with output that ranked first in China in 1999. Commercial crops include citrus fruits, sugar cane, sweet potatoes, peaches and grapes. Sichuan also had the largest output of pork among all the provinces and the second largest output of silkworm cocoons in 1999. Sichuan is rich in mineral resources. It has more than 132 kinds of proven underground mineral resources including vanadium, titanium, and lithium being the largest in China. The Panxi region alone possesses 13.3% of the reserves of iron, 93% of titanium, 69% of vanadium, and 83% of the cobalt of the whole country. Sichuan also possesses China's largest proven natural gas reserves, the majority of which is transported to more developed eastern regions.
Document 8: Peng Yue: In 196 BC, Liu Bang led an army to suppress a rebellion by Chen Xi, the Marquis of Yangxia, and he requested reinforcements from Peng Yue. Peng Yue claimed to be ill and sent his subordinates to help Liu Bang in place of himself. After Chen Xi's rebellion was quelled, Liu Bang heard rumours that Peng Yue was intending to rebel against him as well, and he had Peng arrested. Peng Yue was demoted to the status of a commoner and exiled to the remote Qingyi County (in present-day Ya'an, Sichuan). Along the way, Peng Yue encountered Empress Lü Zhi, who wanted to have him killed. He pleaded with her to spare his life and let him return home to Changyi, and the empress pretended to agree. Peng Yue was brought back to Luoyang where he was subsequently executed. Empress Lü ordered his clan be put to death as well. Peng Yue's corpse was minced into pieces, salted like meat, and distributed to all the noble families of China, who found this very disturbing.
Document 9: Sichuan: In the 20th century, as Beijing, Shanghai, Nanjing, and Wuhan had all been occupied by the Japanese during the Second Sino-Japanese War, the capital of the Republic of China had been temporary relocated to Chongqing, then a major city in Sichuan. An enduring legacy of this move is that nearby inland provinces, such as Shaanxi, Gansu, and Guizhou, which previously never had modern Western-style universities, began to be developed in this regard. The difficulty of accessing the region overland from the eastern part of China and the foggy climate hindering the accuracy of Japanese bombing of the Sichuan Basin, made the region the stronghold of Chiang Kai-Shek's Kuomintang government during 1938-45, and led to the Bombing of Chongqing.
Document 10: Sichuan: The Three Gorges Dam, the largest dam ever constructed, is being built on the Yangtze River in nearby Hubei province to control flooding in the Sichuan Basin, neighboring Yunnan province, and downstream. The plan is hailed by some as China's efforts to shift towards alternative energy sources and to further develop its industrial and commercial bases, but others have criticised it for its potentially harmful effects, such as massive resettlement of residents in the reservoir areas, loss of archeological sites, and ecological damages.
Document 11: Qing dynasty: Widespread drought in North China, combined with the imperialist designs of European powers and the instability of the Qing government, created conditions that led to the emergence of the Righteous and Harmonious Fists, or "Boxers." In 1900, local groups of Boxers proclaiming support for the Qing dynasty murdered foreign missionaries and large numbers of Chinese Christians, then converged on Beijing to besiege the Foreign Legation Quarter. A coalition of European, Japanese, and Russian armies (the Eight-Nation Alliance) then entered China without diplomatic notice, much less permission. Cixi declared war on all of these nations, only to lose control of Beijing after a short, but hard-fought campaign. She fled to Xi'an. The victorious allies drew up scores of demands on the Qing government, including compensation for their expenses in invading China and execution of complicit officials.
Document 12: Sichuan: The majority of the province's population is Han Chinese, who are found scattered throughout the region with the exception of the far western areas. Thus, significant minorities of Tibetan, Yi, Qiang and Nakhi people reside in the western portion that are impacted by inclement weather and natural disasters, environmentally fragile, and impoverished. Sichuan's capital of Chengdu is home to a large community of Tibetans, with 30,000 permanent Tibetan residents and up to 200,000 Tibetan floating population. The Eastern Lipo, included with either the Yi or the Lisu people, as well as the A-Hmao, also are among the ethnic groups of the provinces.
Document 13: Sichuan: Sichuan consists of two geographically very distinct parts. The eastern part of the province is mostly within the fertile Sichuan basin (which is shared by Sichuan with Chongqing Municipality). The western Sichuan consists of the numerous mountain ranges forming the easternmost part of the Qinghai-Tibet Plateau, which are known generically as Hengduan Mountains. One of these ranges, Daxue Mountains, contains the highest point of the province Gongga Shan, at 7,556 metres (24,790 ft) above sea level.
Document 14: Qing dynasty: The reign of the Qianlong Emperor (1735–1796) saw the apogee and initial decline in prosperity and imperial control. The population rose to some 400 million, but taxes and government revenues were fixed at a low rate, virtually guaranteeing eventual fiscal crisis. Corruption set in, rebels tested government legitimacy, and ruling elites did not change their mindsets in the face of changes in the world system. Following the Opium War, European powers imposed unequal treaties, free trade, extraterritoriality and treaty ports under foreign control. The Taiping Rebellion (1850–64) and Dungan Revolt (1862–77) in Central Asia led to the deaths of some 20 million people. In spite of these disasters, in the Tongzhi Restoration of the 1860s, Han Chinese elites rallied to the defense of the Confucian order and the Qing rulers. The initial gains in the Self-Strengthening Movement were destroyed in the First Sino-Japanese War of 1895, in which the Qing lost its influence over Korea and the possession of Taiwan. New Armies were organized, but the ambitious Hundred Days' Reform of 1898 was turned back by Empress Dowager Cixi, a ruthless but capable leader. When, in response to the violently anti-foreign Yihetuan ("Boxers"), foreign powers invaded China, the Empress Dowager declared war on them, leading to defeat and the flight of the Imperial Court to Xi'an.
Document 15: Qing dynasty: Early during the Taiping Rebellion, Qing forces suffered a series of disastrous defeats culminating in the loss of the regional capital city of Nanjing in 1853. Shortly thereafter, a Taiping expeditionary force penetrated as far north as the suburbs of Tianjin, the imperial heartlands. In desperation the Qing court ordered a Chinese official, Zeng Guofan, to organize regional and village militias into an emergency army called tuanlian. Zeng Guofan's strategy was to rely on local gentry to raise a new type of military organization from those provinces that the Taiping rebels directly threatened. This new force became known as the Xiang Army, named after the Hunan region where it was raised. The Xiang Army was a hybrid of local militia and a standing army. It was given professional training, but was paid for out of regional coffers and funds its commanders — mostly members of the Chinese gentry — could muster. The Xiang Army and its successor, the Huai Army, created by Zeng Guofan's colleague and mentee Li Hongzhang, were collectively called the "Yong Ying" (Brave Camp).
