Question: Who led the military expedition in the place where the fight between Ming loyalists and Manchus occurred?

Knowledge 1: Qing dynasty
The Manchus sent Han Bannermen to fight against Koxinga's Ming loyalists in Fujian. The Qing carried out a massive depopulation policy and seaban forcing people to evacuated the coast in order to deprive Koxinga's Ming loyalists of resources, this has led to a myth that it was because Manchus were "afraid of water". In Fujian, it was Han Bannermen who were the ones carrying out the fighting and killing for the Qing and this disproved the entirely irrelevant claim that alleged fear of the water on part of the Manchus had to do with the coastal evacuation and seaban. Even though a poem refers to the soldiers carrying out massacres in Fujian as "barbarian", both Han Green Standard Army and Han Bannermen were involved in the fighting for the Qing side and carried out the worst slaughter. 400,000 Green Standard Army soldiers were used against the Three Feudatories besides 200,000 Bannermen.

In 677 (during the reign of Emperor Gaozong), Chen Zheng (陳政), together with his son Chen Yuanguang (陳元光), led a military expedition to pacify the rebellion in Fujian. They settled in Zhangzhou and brought the Middle Chinese phonology of northern China during the 7th century into Zhangzhou; In 885, (during the reign of Emperor Xizong of Tang), the two brothers Wang Chao (王潮) and Wang Shenzhi (王審知), led a military expedition force to pacify the Huang Chao rebellion. They brought the Middle Chinese phonology commonly spoken in Northern China into Zhangzhou. These two waves of migrations from the north generally brought the language of northern Middle Chinese into the Fujian region. This then gradually evolved into the Zhangzhou dialect.

Li Zicheng then led a coalition of rebel forces numbering 200,000[a] to confront Wu Sangui, the general commanding the Ming garrison at Shanhai Pass. Shanhai Pass is a pivotal pass of the Great Wall, located fifty miles northeast of Beijing, and for years its defenses kept the Manchus from directly raiding the Ming capital. Wu Sangui, caught between a rebel army twice his size and a foreign enemy he had fought for years, decided to cast his lot with the Manchus, with whom he was familiar. Wu Sangui may have been influenced by Li Zicheng's mistreatment of his family and other wealthy and cultured officials; it was said that Li also took Wu's concubine Chen Yuanyuan for himself. Wu and Dorgon allied in the name of avenging the death of the Chongzhen Emperor. Together, the two former enemies met and defeated Li Zicheng's rebel forces in battle on May 27, 1644.

The Qing dynasty (1644–1911) was founded after the fall of the Ming, the last Han Chinese dynasty, by the Manchus. The Manchus were formerly known as the Jurchens. When Beijing was captured by Li Zicheng's peasant rebels in 1644, the Chongzhen Emperor, the last Ming emperor, committed suicide. The Manchus then allied with former Ming general Wu Sangui and seized control of Beijing, which became the new capital of the Qing dynasty. The Mancus adopted the Confucian norms of traditional Chinese government in their rule of China proper. Schoppa, the editor of The Columbia Guide to Modern Chinese History argues, "A date around 1780 as the beginning of modern China is thus closer to what we know today as historical 'reality'. It also allows us to have a better baseline to understand the precipitous decline of the Chinese polity in the nineteenth and twentieth centuries."
Knowledge 1: Nanjing
Zhu Yousong, however, fared a lot worse than his ancestor Zhu Yuanzhang three centuries earlier. Beset by factional conflicts, his regime could not offer effective resistance to Qing forces, when the Qing army, led by the Manchu prince Dodo approached Jiangnan the next spring. Days after Yangzhou fell to the Manchus in late May 1645, the Hongguang Emperor fled Nanjing, and the imperial Ming Palace was looted by local residents. On June 6, Dodo's troops approached Nanjing, and the commander of the city's garrison, Zhao the Earl of Xincheng, promptly surrendered the city to them. The Manchus soon ordered all male residents of the city to shave their heads in the Manchu queue way. They requisitioned a large section of the city for the bannermen's cantonment, and destroyed the former imperial Ming Palace, but otherwise the city was spared the mass murders and destruction that befell Yangzhou.
