In April of the fifth year of Shunzhi (1648), Zheng Chenggong led an army to conquer Tongan County. In seven years, Zheng Lian, who was entrenched in Xiamen, was killed and Xiamen was used as an anti-Qing base. In eight years, Zheng Chenggong led his troops south to Guangdong, and the Qing soldiers attacked Xiamen by taking advantage of weakness. Zheng Chenggong rushed back overnight, executed his uncle Zheng Peng who stayed in Xiamen for dereliction of duty, and returned to Xiamen. In May of ten years, the Qing army attacked Haicheng, and Zheng Chenggong led the army to defend and repel the Qing army. In February of the eleventh year, the Qing court sent envoys in the name of "Hai Chenggong" to impress Zheng Chenggong; In August, the emissary and his brother Du Zheng and Andrew came to surrender. Zheng Chenggong resolutely refused. In the 14th year, Emperor Li Yong of Nanming conferred Zheng Chenggong as the King of Yanping and recruited generals.
15 July, led 10 more than ten thousand troops and dozens of warships, and joined forces with the anti-Qing team under King Lu to start the Northern Expedition. In August, the fleet was hit by the wind off Yangshan, north of Zhoushan, and returned to Zhoushan for repair. In May of the following year, he led his troops from Zhoushan, Liankeguazhou and Zhenjiang to Nanjing. The former naval town led by Zhang Huangyan and Yang Chaodong also returned to Wuhu. Taiping, Ningguo, Chizhou, Huizhou and other four States, three States and twenty-two counties in the lower reaches of the Yangtze River have been attached one after another, and Jiangnan and southern Anhui have once again ignited the anti-Qing bonfire. Seeing the potential crisis, Governor Lang of Nanjing in Qing Dynasty took advantage of the idea of being increasingly paralyzed and underestimating the enemy, and wrote to stop the siege and surrendered voluntarily one month later. Zheng Chenggong believed this promise, but the Qing army secretly deployed it. In late July, Liang Huafeng, the general of the Qing army, led a surprise attack, Zheng Jun was defeated, and Gan Hui and other generals were killed. Zheng Chenggong saw that the tide had receded, so he had to leave the Yangtze River and return to Xiamen. In seventeen years, the Qing court appointed Dasu as a general, mobilized troops from three provinces and attacked Xiamen. Zheng Chenggong fought back and held Xiamen. At this time, the Qing dynasty has gradually formed a national unity situation, and the Qing court can concentrate more troops to surround Zheng Chenggong. Faced with this situation, Zheng decided to recover Taiwan Province Province as a long-term anti-Qing base.
Taiwan Province province was invaded by Dutch colonialists on 1624 (four years from tomorrow) and by Spanish colonialists on 1626. 1642, the Netherlands defeated Spain, occupied the whole island and imposed colonial rule. In March of the 18th year of Shunzhi, Zheng succeeded in setting off from Liaoluo Bay in Jinmen, Fujian, with 25,000 officers and men and hundreds of warships, and arrived at the southwest coast of Taiwan Province Province via Penghu. Landed at Heliao Port near Chiqian (now Tainan City, Taiwan Province Province). In the naval battle, Zheng Jun sank the Dutch main ship hector with a fireboat; In the land war; He also killed Thomas Budd, the leader of the Dutch invading army, and more than 1 10 officers and men. Zheng Chenggong led his troops to besiege Chibi City, forcing the Dutch army commander to cut off water. It's hard to describe, but he can lead the army to surrender on May 4th. Zheng Chenggong continued to attack Taiwan Province Province (now Anping, Taiwan Province Province), the capital of Dutch colonists. The Dutch colonial governor Yi Yi used the city's anti-aircraft guns to fight fiercely and attack the city. Zheng Chenggong commanded troops to besiege the provincial capital of Taiwan Province, while strengthening the political and economic construction in the recovered areas. After learning that Zheng Chenggong led an army to land in Taiwan Province Province, the Chief Executive and the Dutch Colonists' General Review Council sent reinforcements of 12 warships led by Jacob Cowu and 725 soldiers to dock in the city in September, and jointly attacked China warships in Taiwan Province Province Street and nearby with the Dutch army in the city. Under Zheng Jun's resolute counterattack, the Dutch army failed to attack. Kao Wu used the excuse of cooperating with the Qing army to attack Zheng Chenggong's army on the mainland and fled back to Batavia via Siam (now Thailand). Zheng Chenggong besieged Taiwan Province Province for more than eight months. At the beginning of December in the eighteenth year of Shunzhi, he bombarded Wuteli Fort in the east of Taiwan Province Province with artillery, occupied the fort and forcibly attacked the provincial capital of Taiwan Province. On 13, the Dutch colonists finally signed the surrender document containing the clause 18, and soon left Taiwan Province province with the remnants. Zheng Chenggong recovered Taiwan Province Province, which was occupied by Dutch colonists for nearly forty years.
After Zheng Chenggong went to Taiwan Province Province, according to the political system of the mainland, Chiqian was changed to the eastern capital, Tianfu, Tianxing and Wannian counties were set to take charge of the north-south road, and Taiwan Province provinces and cities were changed to Anping Town, and then the appeasement department was set up in Penghu. He cultivated land economically and encouraged "releasing soldiers to agriculture". Attach importance to the development of foreign trade and non-governmental trade, and reward people from the southeast coast of the mainland to settle in Taiwan Province, so as to participate in agricultural production and popularize advanced farming techniques. Due to the reclamation activities of the army and immigrants, new villages and towns soon appeared in western Taiwan, and culture and education also developed.
After recovering Taiwan Province for more than four months, Zheng Chenggong died on the eighth day of May in the first year of Kangxi (1662). During his one year and two months in Taiwan Province Province, he made great contributions to the recovery of Taiwan Province Province and the construction of Taiwan Province Province.
